Popis: The dependence of the 3618.4 cm −1 line assigned to interstitial H 2 in Si on temperature and stress has been studied to probe the structure and microscopic properties of this defect. The H 2 (and D 2 ) stretching lines broaden and shift to lower frequency with increasing temperature while the integrated intensity remains approximately constant. Uniaxial stress results are consistent with triclinic (C 1 ) symmetry and suggest a near 〈1 0 0〉 orientation for the H 2 molecular axis.
