Abstract
Rotational states as functions of pressure for H2, D2, T2 HD, and HT molecules are calculated in the corresponding molecular solids. Sudden transitions from spherically symmetric rotational states occur in para-H2, para-T2, ortho-D2, and in HD and HT as the pressure increases. Only the predicted T2 transition pressure of about 24 kbar lies within current experimentally accessible ranges. All other transitions occur in the region 150–300 kbar.
