Ground and Lowhyphen;Lying Excited Electronic States of FeH

摘要

Manyhyphen;body perturbation theory is used to carry out an approximate Hartreehyphen;Fock calculation on electronic states of FeH with a singlehyphen;center basis set. Approximate potential curves are obtained and used to predict the main features of the spectrum. They are also employed to interpret the known spectra of the ``isoelectronic'' FeCl.
