| Zusammenfassung: | Title screen The infrared spectra of germane, purified and enriched up to 88.1% of 76GeH4, 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-1 where the stretching–bending Tetrad (v1+v2,v1+v4, v2+v3 and v3+v4 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 drms=6.81•10-4 cm-1. The presence of numerous resonance interactions in the Tetrad is discussed. Режим доступа: по договору с организацией-держателем ресурса |
