This project is not yet ready.

The equation-of-motion coupled cluster (EOM-CC) method is an approach to computing the properties of excited states (e.g. excitation energies, oscillator strengths, etc.)^{1)} The central quantity in the EOM-CC method is the similarity-transformed Hamiltonian,

where T is the usual cluster operator. If this (non-Hermitian) operator is used as an approximate Hamiltonian in the Schrödinger equation and the excited-state wave function is written as a linear combination

The EOM-CC method is also capable of computing so-called “response properties” of the ground state, including polarizabilities, magnetizabilities, etc. Such properties will be the subject of later programming projects.
