### Abstract

The infrared spectrum of ^{M}GeH_{4} (M=70,72,73,74,76) was measured at the temperature of (296.75 ± 0.1) K with a Bruker Fourier transform infrared spectrometer IFS125 and analyzed in the region of 1100–1350 cm^{−1} where the ν_{1}−ν_{4}, ν_{3}−ν_{4}, ν_{3}−ν_{2} and ν_{1}−ν_{2} “hot“ bands of GeH_{4} are located. The strengths of 133, 203, 40, 274 and 53 experimentally recorded spectral lines of the ^{70}GeH_{4}, ^{72}GeH_{4} ^{73}GeH_{4}, ^{74}GeH_{4} and ^{76}GeH_{4} isotopologues with the value of quantum number J^{max} = 16, 16, 12, 16 and 14 were determined from the fit of their line shapes with a 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 10 fitted parameters for the ^{74}GeH_{4} isotopologue and only one of the main fitted parameters for the ^{72}GeH_{4} and ^{70}GeH_{4} species (in this case, the values of all other effective parameters were fixed to the values of corresponding parameters of the ^{74}GeH_{4} species) reproduce the initial experimental line intensities with the mean d_{rms}=3.54%. The ^{72}GeH_{4} and ^{70}GeH_{4} species are also analysed. A list of transitions of the four studied “hot“ bands with their line intensities is generated in the HITRAN format up to the value of quantum number J=23.
