High Resolution Study of the v1 + 2v2 −v2 and 2v2 + v3 − v2 ”Hot” Bands and Ro-Vibrational Re-Analysis of the v1 + v2/v2 + v3/3v3 Poliad of the SO2 Molecule
Résumé
The main goal of the present study was to analyse rotational stuctures of two excited vibrational states, (120) and (021). Because both the band,v1 + 2v2 and 2v2 + v3 one are extremally weak, a special efforts were faired to record very weak hot bands, v1 + 2v2 −v2 and 2v2 + v3 −v2 .
