Abstract

ALTHOUGH the gaseous alkaline monofluoride molecules have been known for many years1, the stabilities of these molecules have not been accurately established. The Birge–Sponer extrapolations which Gaydon2 used to arrive at dissociation energies are in doubt because of the limited number of vibrational levels used and the fact that the data were often based on head measurements of bands of a weakly degraded system. Furthermore, these extrapolations are not expected to be normal for such molecules in which ionic forces make an appreciable contribution to the binding. This communication presents new results and theoretical calculations which indicate consistently high dissociation energies for all the alkaline earth monofluorides.
