摘要
The room temperature Raman vibrational modes of isolated H-2, D-2, and HD molecules in GaAs exposed to a H-2, H-2, and H-2:D-2 plasma, have been measured at 3911, 2827, and 3429 cm(-1), respectively. At low temperatures the ortho-para modes of the H-2 line are resolved. Decreasing the temperature to 10 K causes the H-2 Raman frequency to increase by 14 to 3925 cm(-1). A lack of splitting of the H-2 mode under uniaxial stress confirms that the H-2 molecule is free to rotate within the GaAs lattice. [S0163-1829(99)09043-8].
