Nonadiabatic corrections to rovibrational levels of H$_2$

摘要

The leading nonadiabatic corrections to rovibrational levels of a diatomicmolecule are expressed in terms of three functions of internuclear distance:corrections to the adiabatic potential, the effective nuclear mass, and theeffective moment of inertia. The resulting radial Schr\"odinger equation fornuclear motion is solved numerically yielding accurate nonadiabatic energiesfor all rovibrational levels of H$_2$ molecule in excellent agreement withprevious calculations by Wolniewicz.
