Solar Photospheric Models and the Rotational Temperatures of THE C/sub2/ and MgH Molecules

Abstract

Four photospheric models have been utilized to derive model based rotational temperatures of the (0-0) band of the Swan system of C/sub2/ and that of the green system of the MgH molecules. The dissociation energies were varied within reasonable limits to assess their influence on the derived temperatures. It is found that observations are not consistent with the model based results. The need for more refined photospheric models is emphasized.
