| Zusammenfassung: | Title screen The high resolution infrared spectra of MSiD4 (M=29,30) in natural abundance of MSi (92.23% of 28Si, 4.68% of 29Si, and 3.09% of 30Si) were measured with Bruker IFS120 and IFS125 HR Fourier transform infrared spectrometers at an optical resolution between 0.00096 and 0.0025 cm−1 and analyzed in the regions of 550-800 cm−1 and 1480-1700 cm−1 where the four fundamental bands, ν2, ν4, ν1 and ν3are located. The 840/1641/888 transitions with Jmax. = 31/31/35 and 638/1356/838 transitions with Jmax. = 31/31/34 were assigned to the ν2, ν4, and ν3 bands of 29SiD4and 30SiD4. The subsequent weighted fit of experimentally assigned transitions was made with the Hamiltonian model which takes the resonance interactions between pairs of vibrational states (0010, F2)/(1000, A1) and (0001, F2)/(0100, E) into account. As a result, sets of 22 and 22 fitted parameters were obtained which reproduces the initial 3369 and 2832 ro-vibrational transitions of the 29SiD4 and 30SiD4isotopologues with the drms=2.34×10−4 cm−1 and 2.67×10−4 cm−1, respectively. An analysis of 221 and 134 experimental ro-vibrational lines of the ν4/ν2 and ν3bands of 29SiD4 and 30SiD4 was performed using the Hartmann-Tran profile to simulate the measured line shape and to determine experimental line intensities. A detailed line list of transitions of 29SiD4 and 30SiD4 in the studied regions is generated. Режим доступа: по договору с организацией-держателем ресурса |
