Abstract
Comparison of the molecular Qβoptimized and molecular gradient optimized carbon basis sets for CH4 showed that molecular Q optimization is an excellent substitute to the more expensive molecular gradient optimization. The parameter Q of the Q optimization is related to the population (i.e., net charge) on the atom.
