A Study of the Interstellar Diffuse Absorption Featuresm the profiles and structures of the diffuse features, and the correlations with various parameters of the interstellar medium, it is suggested that: (1) the diffuse band . 4430 may be produced by the preionization of H. and, (2) . 5780, 5797 may be due to the pure electronic transitions of the impurity centers in solid grains.
