| Sažetak: | Title screen The high resolution infrared spectra of deuterated hydrogen sulfide D232S were recorded with a Bruker IFS 125HR Fourier transform infrared spectrometer and analyzed in the region of 2400-2900 cm−1 where three ν1+ν2, ν2+ν3 and 3ν2 interacting bands are located. 4227 transitions with maximum values of the quantum numbers Jmax = 28/28/20 and Kamax = 18/19/11 were assigned in the experimental spectra to the ν1+ν2, ν2+ν3 and 3ν2 bands. On this basis, 399/439/216 upper ro-vibrational energies were obtained for the upper vibrational states (110), (011) and (030) (about 43% more for the number of ro-vibrational energy values and about 63% more for the number of assigned transitions compared to preceding studies). These data were used in the weighted fit of the Watson Hamiltonian parameters. The 97 parameters obtained from the fit reproduce the 1054 initial energy values of three vibrational states used in the fit with the root mean square deviation drms=1.97×10−4 cm−1. The 1215 and 56 transitions belonging to the ν1+ν2 and ν2+ν3 bands of the D234S and D233S species (410 and 30 upper energy values, respectively) were recorded and analysed for the first time. The ground vibrational state parameters of D233S are determined from experimental combination differences. Режим доступа: по договору с организацией-держателем ресурса |
