The maximum overlap method (MOM) provides a simple but powerful approach for performing calculations on excited states by targeting solutions with non-Aufbau occupations from a reference set of molecular orbitals. In this work, the MOM is used to acc... Read More about Understanding ground and excited-state molecular structure in strong magnetic fields using the maximum overlap method.
