โฆ Synopsis
Laser-induced excitation spectra of CaAr, SrAr, and BaAr produced in a supersonic jet apparatus were determined m the vicinity of the lowest 'So-'PO resonance lines of the free metal atoms. Spectroscopic constants of the X 'Z + and A %I states of these molecules were determined and compared to those of the analogous MgAr states.
