摘要: The 3618.4 and 2642.6 cm - 1 infrared absorption lines of interstitial H 2 D in silicon have been studied under applied uniaxial stresses. resulting splittings their small dependence on isotope establish that Si is a nearly free rotor these arise from vibrational transitions between rovibrational states with rotational quantum number J = I (T T d symmetry) for ortho-H para-D .
