Spectroscopic constants and potential energy curves of AsF

Spectroscopic constants and potential energy curves of 21 electronic states of AsF are computed using the complete active space self-consistent field (CASSCF) followed by first- and second-order configuration interaction (FOCI, SOCI) and multireference singles and doubles configuration interaction (MRSDCI) methods. The computed spectroscopic constants agree with the experimental values for the observed states.
