Rotational assignments in electronic spectra of large asymmetric rotor molecules

Abstract

A simple method is described for the production of Fortrat diagrams during computation of rotational band contours. Assignments of rotational details in the 0-0 bands of the electronic transitions of phenol at 2750 å and aniline at 2938 å are made with the aid of Fortrat diagrams. Rotational features which may be common in type A and B bands in the electronic spectra of large asymmetric rotor molecules are discussed.
