Jl. Liao et Qs. Zhu, ANOMALOUS INTENSITIES OF LOCAL MODE VIBRATIONAL ABSORPTION OF GERMANEAND A NEW THEORETICAL EXPLANATION, Science in China. Series B, Chemistry, life sciences & earth sciences, 41(2), 1998, pp. 202-206
The (4000), (3100) and (5000) local mode vibrational bands of germane
were recorded with high resolution spectroscopy. The anomalous relativ
e intensities of these bands were found and explained with a bond-bond
coupling dipole moment model. The calculated results, which were also
compared with those from the former theoretical model, agree well wit
h the experimental data.
