Analysis of high excited "hot" bands of the SO2 molecule

2011

The main goal of the present study is to analyse rotational structures of highly excited "hot" vibrational bands, v1+2v2-v2 and 2v2+v3-v2, v2+3v3-v2 and 2v1+v2+v3-v2, and v2+2v3-v2. All of these bands are located in the region of considerably stronger bands, v1 + v2 and v2 + v3, 3v3 and 2v1+v3, and 2v3, respectively . On that reason, as the first step of analysis, we made assignments of transitions belonging to these strong bands. As the result of analysis, we were able to assign three times more transitions to the bands v1 + v2 , v2 + v3, and 3v3 (3360 transitions with Jmax. = 78 and Kmax.a = 27 to the band v1 + v2, and 2380 transitions with Jmax. = 69 and Kmax.a = 24 to the band v2 + v3, …
