摘要
High-resolution (0.05 cm-1) FTIR spectroscopy in the range (9 divided-by 300) K is applied to study the vibrational (stretching, bending and combination) modes of OH- (and its isotopic substitution with OD-) perturbed by a neighbouring defect induced by Mg2+ in LiF and NaF. The stretching-mode spectra are analysed in the framework of the anharmonic-oscillator model: the related Morse parameters have been determined. A model is proposed for the defect, responsible for the stretching line and two bending lines, which are accounted for by an inversion doubling.
