摘要：

RovibrationalQ(J) transitions of the interstitial H-2 molecule in Si have been investigated by Raman scattering in the temperature range 90-388 K. In accordance with an earlier suggestion [M. Hiller, E. V. Lavrov, and J. Weber, Phys. Rev. B 74, 235214 (2006)], it is shown that the Q(2) transition of para hydrogen couples to the TA(X) phonon of Si and appears in the Raman spectra at temperatures above 200 K. The results presented also indicate that the rotational J = 3 state of ortho hydrogen is resonantly coupled to the O-Gamma phonon.
