Abstract
The linear and quadratic response functions have been determined for a coupled cluster reference state. From the response functions, computationally tractable expressions have been derived for excitation energies, first- and second-order matrix transition elements, transition matrix elements between excited states, and second- and third-order frequency-dependent molecular properties. © 1990 American Institute of Physics.File in questo prodotto:
