“This gives an overall theoretical model which is computationally efficient and which can be applied to a wide range of chemical problems.”

“My own contributions to this field have been in the development of a systematic hierarchy of theoretical models.”

“Such a theoretical model chemistry is specified by a theoretical method and a basis set.”

“We are trying to make a theoretical model of the real world.”

“The objective is to test the theory by comparison with experiment. If the theory is deficient, it has to be improved.”
