✦ Synopsis


Rotational term values for the highly asymmetric (\mathrm{H}_{2} \mathrm{D}^{+})molecule are calculated variationally from first principles using an accurate potential energy surface. Fits are performed using the conventional Watson (A)-reduced and PadΓ© forms of effective Hamiltonians. A sixth-order PadΓ© fit gives satisfactory assignments for the vibrational ground state rotational levels up to (J=25), in contrast to previous studies, and assignments for levels up to (J=30). The hehavior of conventional effective Hamiltonians for these levels is also discussed. (c) 1993 Academic Press, Inc.
