Modern Electronic Structure Theory: The Search For Chemical Accuracy, Jonathan Prince

Boise State University Theses and Dissertations

Electronic structure theory has progressed significantly within the last few decades, venturing far from the early days of the Hartree-Fock self-consistent field method. Modern electronic structure theory focuses on compound methods, which operate under the idea that we can take a lower level of theory computation (typically, a result from Hartree-Fock, Configuration Interaction, Coupled Cluster or Moller-Plesset perturbation theory) and add in higher level of the theory corrections such as extrapolations to the infinite basis set limit, as well as, relativistic effects.

Using the Gaussian-n, Complete Basis Set and Weizmann compound methods, we were able to provide theoretical evidence to …
