Rotational motion under pressure in the solid molecular hydrogen isotopes

Rotational states as functions of pressure for H$sub 2$, D$sub 2$, T$sub 2$, HD, and HT molecules are calculated in the corresponding molecular solids. Sudden transitions from spherically symmetric rotational states occur in para- H$sub 2$, para-T$sub 2$, ortho-D$sub 2$, and in HD and HT as the pres...

Zusammenfassung:	Rotational states as functions of pressure for H$sub 2$, D$sub 2$, T$sub 2$, HD, and HT molecules are calculated in the corresponding molecular solids. Sudden transitions from spherically symmetric rotational states occur in para- H$sub 2$, para-T$sub 2$, ortho-D$sub 2$, and in HD and HT as the pressure increases. Only the predicted T$sub 2$ transition pressure of about 24 kbar lies within current experimentally accessible ranges. All other transitions occur in the region 150-300 kbar. (auth)
