Abstract
Investigation of the absorption spectra of the alkaline earth fluorides under high dispersion reveals several new band systems in the ultraviolet region as far as . Vibrational analyses of these systems give the vibration frequencies and electronic terms of one new state of MgF, three of CaF, four of SrF, and four of BaF. Some changes in the previous analyses of the system of MgF and the system of CaF are made. An increased binding in all of these higher energy states as indicated by the values of the constants is discussed with regard to the probable electron configurations.
