	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 = {Preliminary results of a high resolution coherent vacuum ultraviolet study of photoion-pair formation in HF/DF are reported. These results include threshold ion-pair production (TIPPS) and total photoion-pair yield spectra, which show sharp resonances due to predissociating Rydberg states. Detailed analysis of the spectra provides precise energies for the ion-pair thresholds, and insight into the mechanism for ion-pair formation.},

	abstract = {Threshold ion-pair production spectroscopy (TIPPS) has been applied to two isotopomers, HCl and DCl. From the high-resolution TIPP spectra the ion-pair thresholds of the two molecules have been precisely measured. Combined with the known ionization energy of H(D) and the electron affinity of Cl, the difference between their bond dissociation energies is calculated, and therefore an experimental determination of the effect of Born-Oppenheimer breakdown on the dissociation limit of the ground state potential curve has been obtained. The difference in D-e for the two isotopomers was found to be: D-e(H-Cl)-D-e(D-Cl)=3.2+/-1.0 cm(-1). The bond energy for HCl was in agreement with our previous determination, D-0(H-Cl)=35748.2+/-0.8 cm(-1). These results are compared to a recent study of Born-Oppenheimer breakdown in HCl by Coxon and Hajigeorgiou, where high resolution spectroscopic data was used to fit Born-Oppenheimer breakdown correction terms for the intramolecular potential function. The present study also measured the high resolution spectra for photoion-pair production for HCl and DCl in the threshold region for ion-pair production (similar to86 nm). Although there is qualitative agreement between the current results and previous experimental and theoretical work, there are some important differences. The possible mechanism for ion-pair formation in HCl and DCl is discussed in light of these high resolution results. (C) 2003 American Institute of Physics.},

	abstract = {The rotational spectrum of the van der Waals complex OCCl2 has been observed in the frequency range 5-12 GHz using a cavity-pulsed microwave Fourier transform spectrometer. The isotopomers investigated were (OCCl2)-Cl-35, (OCClCl)-Cl-37-Cl-35, (OCClCl)-Cl-35-Cl-37, (OCCl2)-C-13-Cl-35, (OCClCl)-C-13-Cl-37-Cl-35, (OCClCl)-C-13-Cl-35-Cl-37, and (OCCl2)-O-18-C-13-Cl-35. It is established that the complex is linear in the ground vibrational state, and a complete substitution (r(s)) structure has been obtained. The nuclear quadrupole hyperfine structures due to the Cl-35 and Cl-37 nuclei have been resolved, yielding the corresponding nuclear quadrupole coupling constants. The differences in these constants between the inner and outer Cl nuclei, along with the derived geometry and the relatively low centrifugal distortion constants, are consistent with a picture of a rather rigid complex with a significant charge redistribution in the Cl2 monomer on complexation with CO.},
