Riassunto:Title screen
The weak “hot” absorption bands, ν1+2ν2−ν2 and 2ν2+ν3−ν2, were analysed with high resolution using the Fourier transform interferometer Bruker IFS-120 HR. In order to make possible an analysis of theν1+2ν2−ν2 and 2ν2+ν3−ν2 bands, as the first step, we re-analysed considerably the stronger “cold” bands, ν1+ν2 and ν2+ν3, which are located in the same spectral regions. As the result of analysis we obtained about 2650 and 2050 transitions (1069 and 1001 upper state ro-vibrational energy values) withJmax. = 78, Kamax. = 27 and Jmax. = 68, Kamax. = 24 for the bands ν1+ν2 and ν2+ν3, respectively, that is considerably higher than in the earlier studies of corresponding bands (Jmax. = 33, Kamax. = 7 and Jmax. = 50,Kamax. = 16 for the same bands, ν1 ν2 and ν2+ν3, respectively). A strong local resonance interaction with the 3ν2 band was taken into account, and the set of parameters that reproduce the initial experimental data with an accuracy close to experimental uncertainties, was obtained. The weak ν1+2ν2−ν2 and2ν2+ν3−ν2 bands were assigned, and about 870 and 930 transitions (553 and 540 upper state ro-vibrational energy values) with Jmax. = 60 and Kamax. = 20 and Jmax. = 59 and Kamax. = 16 were assigned to the ν1+2ν2−ν2 and 2ν2+ν3−ν2 bands, respectively. A complete list of assigned transitions is presented, and corresponding spectroscopic parameters are obtained from the fit of assigned transitions (upper energy values).
