摘要：

The integrated intensities of the absorption lines due to local vibrational modes of defects of T(d) and C3v symmetry are calculated as a function of the parameter measuring the strength of the coupling between the mode and the electric field associated with the light beam. In the case of C3v symmetry defects, the derivation does not assume this parameter to be the same for the longitudinal and transverse modes. The model is applied to the centres resulting from the neutralization by hydrogen of shallow dopants in crystalline semiconductors.
