	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.},

The rotational structures are analyzed for both isotopic species to obtain precise rotational and spin constants. Two new bands at 27 032.222(1) and 27 515.41(1) cm-1 arising from vibronic interaction separately with vibrational state (110) and (200) of (a) over tilde B-3(1) are assigned to transitions to (b) over tilde (3)A(2)(011) and (101). The rotational structure of (b) over tilde (3)A(2) is observed and analyzed for the first time. The two vibrational states are analyzed to yield effective rotational constants A=1.4348(3), 1.89(3)},

	abstract = {Laser excitation of isotopically labeled SO2 molecules in a neon matrix has allowed the measurement of dispersed phosphorescence spectra ((a) over tilde(3)B(1)-(X) over tilde(1)A(1)) in the wavelength region 387.5-526.3 nm (19 000-25 800 cm(-1)). The origin of the (a) over tilde-(X) over tilde transition lies at 25 747 cm(-1) in (OSO)-O-16-O-16, shifted 18 cm(-1) to the red from the gas phase; the three vibrational frequencies of the (X) over tilde state are nearly unperturbed in the neon matrix (1149, 520, and 1362 cm(-1)). As the zero-phonon lines are sharp and well resolved, it has been possible to monitor emission from a specific isotopomer to obtain its excitation spectrum. The excitation spectra of matrix-isolated (OSO)-O-16-O-16 and (OSO)-O-18-O-18 in the region 350.9-388.5 nm (25 740-28 500 cm(-1)) are similar to those previously observed in the gas phase, with strong perturbations affecting all vibrational levels above a(3)B(1)(110) at 27 005 cm(-1) (370 nm). Two additional groups of bands are observed for the unsymmetrical isotopomer (OSO)-O-18-O-16; they are identified as transitions to levels of the (a) over tilde(3)B(1) state with v(3) = 1 and as direct transitions to the (b) over tilde(3)A(2) state, which both become allowed in the lower symmetry. The v(3) frequency of the (a) over tilde(3)B(1) state of (OSO)-O-18-O-16 is 922 cm(-1); for the (b) over tilde(3)A(2) state, v(1) similar or equal to 791 cm(-1) and v(2) similar or equal to 315 cm(-1), while the (b) over tilde (001) level lies 26 653 cm(-1) above the (X) over tilde (000) level.},

Transitions in the ground and first excited vibrational states have been measured for both the (YBr)-Br-79 and (YBr)-Br-81 isotopomers. Equilibrium rotational parameters have been determined and an equilibrium bond distance has been calculated. Vibrational parameters have been estimated. Hyperfine structure due to the bromine nuclei has been observed and nuclear quadrupole and nuclear spin-rotation constants have been determined. These parameters have been used to investigate the ionic character of the Y-Br bond and comparisons have been made to several alkali and alkaline earth metal bromide species.
