Phys. 137, 154305 (2012); 10.1063/1.4757859 An empirical potential energy surface for the Ne-OH/D complexes High resolution electronic spectroscopy and an empirical potential energy surface for NeSH/D The high resolution laser-induced fluorescence spectra of the Kr•OH van der Waals complex and its deuterated analog are reported. The rotational analysis provides information about the observed fine, hyperfine, spin-rotation, and parity interactions in these two complexes. The molecular parameters allow a direct comparison with previously reported results on the analogous Kr•SH/D complexes. Additionally, lower resolution scans have revealed vibronic bands that have not been reported in the previous work of Fei, Zheng, and Heaven ͓J. Chem. Phys. 97, 1655 ͑1992͔͒, while high resolution results of the 86 Kr•OH/D, 84 Kr•OH/D, and 82 Kr•OH/D isomers confirmed the previous vibrational quantum number assignment. The results of the high resolution analysis are used in conjunction with measured vibrational intervals to develop an empirical potential energy surface for Kr•OH/D. This is compared to the recently reported potentials by Korambath et al. ͓J. Chem. Phys. 107, 3460 ͑1997͔͒ for the other R•SH/D ͑RϭAr, Kr͒ complexes.

Electronic Quenching of OH A 2Σ+ Induced by Collisions with Kr Atoms

“…Kr system have been focused on the OH-Kr van der Waals complex formed when the H-side of OH X 2  interacts with Kr and its subsequent electronic excitation. [32][33][34][35] High-resolution electronic spectroscopy studies by Miller and coworkers enabled analysis of several vibronic bands of OH-Kr on the A 2  + -X 2  transition. 32,33 These authors derived rotational constants and bond lengths for the ground state and several vibronic levels in the excited electronic state.…”

In addition, they characterized intermolecular stretch progressions with and without bend excitation in the excited electronic state.…”

“…In recent years, the electronic spectroscopic study of van der Waals complexes containing open-shell diatoms interacting with a closed-shell atom has attracted some attention, with the majority of studies concentrating on the lowest energy (allowed) transition. Interestingly, many of the detailed studies have focused on OH- and SH-containing complexes, − whereas complexes containing the stable NO radical have only recently attracted some notice. Much attention has been focused on the à state of Rg·NO complexes (Rg = rare gas), − but there has also been significant progress in the understanding of the spectra of the higher (C̃, D̃, and Ẽ) electronic states. − Studies have also been performed on complexes containing a closed-shell molecule interacting with an open-shell diatomic partner, with those on H 2 ·OH being the most detailed .…”
