A comparative study of RKRV and reduced potential curves of the ground states of alkaline-earths chlorides

In light of the recording and analyzing of high resolution FT spectrum of MgCl molecule, a comparative study of the RKRV and RP curves of the ground states of alkaline earth chloride viz. BeCl, MgCl, CaCl, SrCl and BaCl have been made using latest molecular constants. The H-H and extended Rydberg potential functions compete each other and have excellent agreement with RKRV curves for all the molecules. Because of the use of improved constants the Potential Energy curves in present study are better as compared to earlier workers.
