	abstract = {Rotational analyses are reported for the 2(0)(2) and 1(0)(1) bands of the (A) over tilde (1) A(u) <- (X) over tilde (1) Sigma(+)(g) transition of C2H2 near 45,000 cm(-1) (+2800 cm(-1) relative to T-0) from jet-cooled laser-induced fluorescence spectra. While the 220 band is unperturbed and straightforward to assign, the 1(1) level is strongly perturbed by interactions with the 2(1) B-2 polyad, where upsilon B{\textquoteright} = upsilon(4){\textquoteright} + upsilon(6){\textquoteright}. In order to assign the lines of this band, a population-labelling technique was used, employing an infrared laser to deplete the population in selected ground state rotational levels before probing with the ultraviolet laser. Deperturbation of the 1(1)/2(1) B-2 interaction leads to the value v(1){\textquoteright} = 2880.08 cm(-1) for the fundamental symmetric C-H stretching frequency. Assignments are also reported for the 2 3 and 1 1 2 1 levels, completing all assignments of levels containing excitation in only the totally symmetric vibrational modes up to + 4500 cm(-1). The reassignment of upsilon(1){\textquoteright} implies that some of currently accepted assignments above 47,000 cm(-1) are in error and suggests that the interpretation of some aspects of the near-threshold photodissociation measurements of Mordaunt et al. [J. Chem. Phys. 108, 519 (1998)] may need to be revisited.},

	abstract = {We measured excess chemical potentials, mu (E)(i), excess partial molar enthalpy, H-i(E), of solute i in aqueous acetone and tetramethyl urea (TMU). We then evaluated excess partial molar entropy, S-i(E). They all were determined accurately and in small increments in mole fraction, and hence, it was possible to take one more derivative with respect to mole fraction. These higher derivatives were used to learn more about intermolecular interaction in solution. Furthermore, they were used to detect anomalous thermodynamic behaviour, in particular a qualitative change in mixing scheme. We conclude that in both aqueous solutions, three distinctively different mixing schemes are operative depending on the composition range, and that in the most H2O-rich region, solute molecules enhance the hydrogen bond network of H2O in their immediate vicinity. However, the hydrogen bond probability in the bulk of H2O away from solute is reduced. (C) 2000 Elsevier Science B.V. All rights reserved.},
