POTENTIAL ENERGY CURVES AND DISSOCIATION PRODUCTS OF THE K2 MOLECULE

Abstract
A R.K.R.V. calculation has been performed for the and B1Πu state of the K2 molecule. By fitting an empirical potential curve to the known true potential curve (the one obtained by the R.K.R.V. method) the dissociation energies of the corresponding states can be estimated. These estimated values allow the states of the dissociated atom to be determined. We have used the four-parameter Lippincott and the five-parameter Hulburt–Hirschfelder functions to approximate the R.K.R.V. curves of the two states. The agreement between the curves is of the same type as already found in previous cases.
