On effectiveness of Morse and Lippincott potential functions forA andX states of MgH

Molecular properties like potential curve,r-centroids, dissociation energy for theA ²II-X ² Σ band system of MgH are studied using Morse and Lippincott functions. Calculations for potential curve and dissociation energy indicate that the Lippincott function is not very appropriate forA andX states of MgH.r-centroids calculated using graphical as well as numerical methods agree well with each other. A smooth relationship between wavelength andr-centroid is obtained. Based on the dissertation submitted to the South Gujarat University by GKP in partial fulfilment of M. Phil. degree, 1976.
