## Abstract Gradient optimized constrained (2__s__ β 2__p__) and unconstrained (2__s__ β 2__p__) Gaussian 3G basis sets are reported for the firstβrow atoms and ions __X__^__O__^, for __Q__ = β2 to +4. Analytic equations have been fitted to the logarithm of the exponents as a function of the nuclea
## Abstract Information theory can be used to evaluate the quality of a wave function by considering its ability to give values for some observables as close as possible to the experimental ones. A new method for improving the quality of a wave function is proposed. This paper deals exclusively wit
