We present the results of theoretical calculations of the structure, diffusion and rotational energies, and the ro-vibrational modes of the hydrogen molecule in the hexagonal part of 4H-SiC and in 2H-GaN. In both materials, the molecule is stable and aligned along the c-axis. Its rotational barrier is sufficiently large that ortho- and para-forms have almost degenerate ro-vibrational modes. The origin of two modes at 4090 and 4110 cm-1 attributed to molecules observed by multi-transmission FTIR experiments on Mg doped insulating GaN grown by OMVPE is discussed. © 2003 Elsevier B.V.
