Izvleček:	Title screen The high resolution infrared spectra of SiH4were recorded with Bruker IFS120 and IFS125 HR Fourier transform infrared spectrometers at an optical resolution of 0.0021 and 0.0025 cm−1and analyzed in the region of 1600-2100 cm−1where the first bending overtone 2ν2,2ν4and combinational ν2+ν4bands are located. The number of 640/1114/2667 transitions with Jmax= 23 were assigned to the bands 2ν2(A1- and E-type sub-bands), 2ν4(A1-, E- and F2-type sub-bands) and ν2+ν4(F1- and F2-type sub-bands) of the 28SiH4molecule. The subsequent weighted fit of experimentally assigned transitions was made with the Hamiltonian model which takes the resonance interactions between seven vibrational states ((0200,A1),(0200,E),(0101,F1),(0101,F2),(0002,A1),(0002,E)and (0002,F2)) into account. As the result, a set of 73 fitted parameters was obtained which reproduces the initial 4421 experimental transitions with the drms=3.31×10−4 cm−1. On the basis of the obtained results, 4940 hot transitions were assigned in the high resolution spectra of the Dyad region studied before. The corresponding analysis was made for the 29SiH4and 30SiH4isotopologues. A line list of 12,698 experimental transitions for both the “cold” and “hot” transitions of all three isotopologues is presented. Режим доступа: по договору с организацией-держателем ресурса
