چکیده انگلیسی
High-resolution Fourier-transform absorption spectra of nitrous acid (HONO) were recorded in the 400-700 cmâ1 spectral region. For the trans-HONO isomer a very extensive analysis of the ν5 (ONO bend) and ν6 (torsion) interacting fundamental bands of trans-HONO located near 595.620 and 543.879 cmâ1, respectively, was performed starting from the results of a previous study [C.M. Deeley, I.M. Mills, L.O. Halonen, J. Kauppinen, Can. J. Phys. 63 (1985) 962-965]. In addition, for the less abundant cis-HONO isomer, the first high-resolution study of the ν6 band located at 639.7432 cmâ1 was achieved, the ν5 band is presumed to be located near 609.2 cmâ1. For both isomers the strong A-type and B-type Coriolis interactions linking the {51, 61} interacting energy levels were accounted for during the energy level calculations. Finally, using these results a list of positions and of realistic relative line intensities has been generated for both isomers, and a comparison with some ab initio predictions was performed.
