	abstract = {Rotational analyses have been carried out at high resolution for the 000-000 and 000-100 bands of the A (1)Pi(u)-X (1)Sigma(g)(+) transition of supersonic jet-cooled C-3. Two different spectra have been recorded for each band, using time gatings of 20-150 and 800-2300 ns. At the shorter time delay the spectra show only the lines observed by many previous workers. At the longer time delay many extra lines appear, some of which have been observed previously by [McCall Chem. Phys. Lett. 374, 583 (2003)] in cavity ring-down spectra of jet-cooled C-3. Detailed analysis of these extra lines shows that at least two long-lived states perturb the A (1)Pi(u), 000 state. One of these appears to be a (3)Sigma(u)(-) vibronic state, which may possibly be a high vibrational level of the b (3)Pi(g) state, and the other appears to be a P=1 state with a low rotational constant B. Our spectra also confirm the reassignment by McCall of the R(0) line of the 000-000 band, which is consistent with the spectra recorded towards a number of stars that indicate the presence of C-3 in the interstellar medium. Fluorescence lifetimes have been measured for a number of upper-state rotational levels. The rotational levels of the A (1)Pi(u) state have lifetimes in the range of 230-190 ns, decreasing slightly with J; the levels of the perturbing states have much longer lifetimes, with some of them showing biexponential decays. An improved value has been obtained for the nu(1) vibrational frequency of the ground state, nu(1)=1224.4933 +/- 0.0029 cm(-1). (c) 2005 American Institute of Physics.},

	abstract = {Using an atomic force microscope (AFM), we have investigated the interaction forces exerted by latex particles bearing densely grafted polymer brushes consisting of poly(N,N-dimethylacrylamide) (PDMA), poly(methoxyethylacrylamide) (PMEA), poly(N-isopropylacrylamide) (PNIPAM), and PMEA-b-PNIPAM in aqueous media (good solvent). The brushes were prepared by controlled surface-initiated atom transfer radical polymerization, and the hydrodynamic thicknesses were measured by dynamic light scattering. The molecular weight (M-n), grafting density (sigma), and polydispersity (PDI) of the brushes were determined by gel permeation chromatography and multiangle laser light scattering after cleaving the polymer from the latex surface by hydrolysis. Force profiles of PDMA (0.017 nm(-2) less than or equal to sigma less than or equal to 0.17 nm(-2)) and PMEA (sigma = 0.054 nm(-2)) brushes were purely repulsive upon compression, with forces increasing with M-n and sigma, as expected, due to excluded volume interactions. At a sufficiently low grafting density (sigma = 0.012 nm(-2)), PDMA exhibited a long-range exponentially increasing attractive force followed by repulsion upon further compression. The long-range attractive force is believed to be due to bridging between the free chain ends and the AFM tip. The PNIPAM brush exhibited a bridging force at a grafting density of 0.037 nm(-2), a value lower than the sigma needed to induce bridging in the PDMA brush. Bridging was therefore found to depend on grafting density as well as on the nature of the monomer. The grafting densities of these polymers were larger than those typically associated with bridging. Bridging interactions were used to confirm the presence of PNIPAM in a block copolymer PMEA-b-PNIPAMA brush given that the original PMEA homopolymer brush produced a purely repulsive force. The attractive force was first detected in the block copolymer brush at a separation that increased with the length of the PNIPAM block.},

	abstract = {The accuracy of the molecular weights M-n and polydispersities of polymer brushes, determined by stretching the grafted chains using atomic force microscopy (AFM) and measuring the contour length distribution, was evaluated as a function of grafting density sigma. Poly(NN-dimethylacrvlamide) brushes were prepared by surface initiated atom transfer radical polymerization on latex particles with a ranging between 0.17 and 0.0059 chains/nm(2) and constant M-n. The polymer, which could be cleaved from the grafting surface by hydrolysis and characterized by gel permeation chromatography (GPC), had a M-n of 30 600 and polydispersity (PDI) of 1.35. The M-n determined by the AFM technique for the higher density brushes agreed quite well with the GPC results but was significantly underestimated for the lower sigma. At high grafting density in good solvent, the extended structure of the brush increases the probability of forming segment-tip contacts located at the chain end. When the distance between chains approached twice the radius of gyration of the polymer, the transition from brush to mushroom structure presumably enabled the formation of a larger number of segment-tip contacts having separations smaller than the contour length, which explains the discrepancy between the two methods at low sigma. The PDI was typically higher than that obtained by GPC, suggesting that sampling of chains with above average contour length occurs at sigma frequency that is greater than their spatial distribution.},

Proton nuclear magnetic resonance (NMR) T-1(-1) relaxation rates have been measured for the C12E6/D2O system as a function of composition, spectral frequency, and temperature. The results are interpreted in terms of the possible molecular motions for the C12E6 molecule in the different phases. A review of relaxation theory is presented with special attention to molecular exchange between sites that are associated with different relaxation rates.},

The X-ray crystal structure shows the scandium centre to reside in a square pyramidal environment with the [N((SiMe2CH2PPr2)-Pr-i)(2)] - ligand bound in a pseudo-meridional fashion. The H-1 NMR spectrum is consistent with a C-s symmetric structure in solution. Metathesis of the chloride ligand with RLi (R = Me, Ph, BH4) yields the five-coordinate species Sc(eta(5)-C5H5)R[N((SiMe2CH2PPr2)-Pr-i)(2)]. Phenyl 3 and borohydride 4 are isolated as crystalline solids, while methyl 2 resisted crystallization. 2-4 exhibit H-1 NMR spectra consistent with C-s symmetric solution structures. Sc(eta(5)-C5H5)Ph[N((SiMe2CH2PPr2)-Pr-i)(2)] (3) was characterized in the solid state and found to have a similar geometry to that of the parent chloride. Reaction of Sc(eta(5)-C5H5)Me[N((SiMe2CH2PPr2)-Pr-i)(2)] (2) with NH2R (R = Ph, Bu-t) yields the amides Sc(eta(5)-C5H5)NHPh[N((SiMe2CH2PPr2)-Pr-i)(2)] (5) and Sc(eta(5)-C5H5)(NHBu)-Bu-t- [N((SiMe2CH2PPr2)-Pr-i)(2)] (6) via sigma-bond metathesis routes; these reactions are accompanied by a competing reaction at the scandium-amide bond to produce the protonated ligand, HN((SiMe2CH2PPr2)-Pr-i)(2) 5 and 6 are also produced by salt-elimination from the chloride 1 and LiNHR (R = Ph, Bu-t). Sc(eta(5)-C5H5)(BH4)[N((SiMe2CH2PPr2)-Pr-i)(2)] (4) reacts with PMe3 to produce the putative hydride, Sc(eta(5)-C5H5)H[N((SiMe2CH2PPr2)-Pr-i)(2)] (7); this species was identified in solution. An equilibrium between 4, PMe3, 7, and PMe3,BH3 exists which greatly favors the starting scandium-borohydride. Crystals of Sc(eta(5)-C5H5)Cl[N((SiMe2CH2PPr2)-Pr-i)(2)] (1) are monoclinic},

The magnetic properties were analyzed employing a model for S = 1 which takes into account zero-field splitting and employs a molecular field term to account for weak magnetic exchange. The compounds Ni(pyz)Cl-2 and Ni(py)Cl-2, show metamagnetic behaviour with critical fields of 13 and 2 kOe, respectively, at 2 K. In these compounds nickel ions, linked in chains by bridging chlorides, exhibit intrachain ferromagnetic and interchain antiferromagnetic exchange. In Ni(pyz)Cl-2, bridging pyrazine ligands are considered to provide the pathway for the antiferromagnetic coupling resulting in a high critical field.},
