The infrared spectra of germane, purified and enriched up to 88.1% of GeH, was measured at the temperature of (22.6±0.1) °C and different pressures with a Bruker Fourier transform infrared spectrometer IFS125HR and analyzed for the first time in the region of 2700-3200 cm where the stretching-bending Tetrad (ν+ν,ν+ν, ν+ν and ν+ν bands) of the ro-vibrational Octad of germane is located. The 3595 transitions belonging to the eight sub-bands of the Tetrad were assigned and theoretically analysed in the frame of the effective Hamiltonian model. The obtained set of 106 fitted parameters reproduces the initial 3595 experimental line positions with the d=6.81×10 cm. The presence of numerous resonance interactions in the Tetrad is discussed.
使用布鲁克傅里叶变换红外光谱仪IFS125HR，在(22.6±0.1) °C的温度和不同压力下，测量了纯度高达88.1%的锗烷（GeH）的红外光谱，并首次在2700 - 3200 cm区域进行分析，该区域是锗烷转动振动八重态的伸缩弯曲四重态（ν + ν、ν + ν、ν + ν和ν + ν带）所在之处。属于四重态八个子带的3595个跃迁被指定，并在有效哈密顿模型框架内进行了理论分析。获得的一组106个拟合参数以d = 6.81×10 cm再现了最初的3595个实验谱线位置。讨论了四重态中大量共振相互作用的存在情况。
