	abstract = {Threshold ion-pair production spectroscopy (TIPPS) has been applied to two isotopomers, HF and DF. From the high resolution (similar to 0.3 cm(-1)) TIPP spectra, the ion-pair thresholds of HF/DF have been precisely measured. Combined with the ionization energy of H(D), the electron affinity of F, and the zero point energies of HF/DF, the difference between their classical bond dissociation energies was obtained as D-e(H-F)-D-e(D-F)=12.4 +/- 0.5 cm(-1). Our result provides an experimental estimate of the Born-Oppenheimer breakdown in the ground electronic state. The present work also measured the total ion-pair yield spectra of HF and DF in the threshold region, and the ion-pair formation mechanisms of these two molecules were discussed in light of the high resolution results.},

	abstract = {The diatomic molecules BiN and BiP have been prepared using a laser ablation technique and studied by Fourier transform microwave spectroscopy in the frequency range 7-22 GHz. For BiN, only the J = 1-0 transition fell within this range. Transitions for the ground and first excited vibrational states have been observed for both (BiN)-N-14 and (BiN)-N-15. For BiP, which has only one isotopomer, the transitions J{\textquoteright}-J" = 1-0. 2-1 and 3-2 have been observed, but only for the ground vibrational state. Hyperfine structure has been observed for both nuclei in both molecules the Bi-209 nuclear quadrupole coupling constants show that the electronic structures are similar for the two molecules. Improved bond lengths have been obtained for both molecules. Density functional methods have been used to estimate the electron density at the bismuth nucleus in each molecule and hence allow an estimate of the uncertainty due to field shift effects in the experimentally derived bond lengths.
