| Summary: | Title screen Absolute line strengths of 28SiH4 were measured for the first time with a Bruker Fourier transform infrared spectrometer IFS120HR and analyzed in the 1180–1360 cm−1 region where the 𝜈1 − 𝜈4 , 𝜈3 − 𝜈4 , 𝜈3 − 𝜈2 and 𝜈1 − 𝜈2 ’’hot‘‘ bands of SiH4 are located. The strengths of 429 isolated nonsaturated and not too weak (i.e., which transmittances for the present experiment are no more than 97 per cent) spectral lines with the value of quantum number 𝐽 max = 18, 14, 13, 13 for the bands 𝜈1 −𝜈4 , 𝜈3 −𝜈2 , 𝜈1 −𝜈2 , and 𝜈3 −𝜈4 were obtained from the fit of their line shapes with a Voigt and Hartmann–Tran line profile and were used then in the weighted fit for determination of the effective dipole moment parameters of the studied ’’hot‘‘ bands. The obtained set of 5 fitted parameters reproduces the initial experimental line strengths with the 𝑑rms = 5.7%. A list of the analyzed transitions with their line intensities is presents as the Supplementary data to this paper Текстовый файл AM_Agreement |
