mp2_get_term_info(excitation_list, freeze_core=False, orbital_reduction=None)¶
With a reduced active space the set of used excitations can be less than allowing all available excitations. Given a (sub)set of excitations in the space this will return a list of correlation coefficients and a list of correlation energies ordered as per the excitation list provided.
excitation_list (list) – A list of excitations for which to get the coeff and e_delta
freeze_core (bool) – Whether core orbitals are frozen or not
orbital_reduction (list) – An optional list of ints indicating removed orbitals
List of coefficients and list of energy deltas
ValueError – Excitation not present in mp2 terms
