The infrared spectrum of germane, purified and enriched up to 88.1% of 76GeH4, was measured at the temperature of (22.6±0.1)∘C with a Bruker Fourier transform infrared spectrometer IFS125HR and analyzed in the region of 2350–2730 cm−1 where the bending tetrad of the ro-vibrational octad of germane is located. The 2955 transitions belonging to the thirteen sub-bands of the Tetrad were assigned and theoretically analysed in the frame of the effective Hamiltonian model. The obtained set of 98 fitted parameters reproduces the initial 2955 experimental line positions with the drms=6.43×10−4 cm−1. A list of assigned experimental transitions is presented as the Supplementary material to the present paper.
