A U(2) algebraic model is presented to describe stretching vibrations of XY n (n Ο 2, 3, and 4) systems, where anharmonic interactions between the bond modes are considered. This model in a limit corresponds to an anharmonically coupled local-mode model. As an example, the model for a molecule XY 4

The three u(CH or CD) fundamentals of pyrazole-Do (la) NH-N=CH-CH=CY, of its deuterated NH species, -4-D1 (2a), -3,5-D2 (3a), -3,4,5-D3 (4a), and ND species, -l-D1 (lb), -1,4-D2 (2b), -1,3,5-D3 (3b), -D4 (4b), were obtained by Raman spectroscopy. Each a, b couple (Le. la, lb, etc.) gives identical u
The infrared spectra of the NH 2 stretching modes of aniline-Ar n (n ~ 1, 2) clusters and corresponding cluster cations in a supersonic jet have been observed using an IR-REMPI double resonance technique. The observed frequencies of the 1 + aniline-Ar cluster are ~sym = 3422, and Uasy m ~ 3508 cm-,
