Theoretical vibration–rotation coefficients for tritiated and deuterated [Formula: see text] are reported for Carney and Porter's ab initio electronic CI potential energy surface. In the calculation of coefficients connecting the zero-point and fundamental states of vibration, accurate vibrational CI wave functions, consisting of 220 configuration functions, were used.
