The superscript e before A₁ and B₂ has been used to distinguish the purely electronic ^eA₁ and ^eB₂ states, respectively, from the vibronic A₁ and B₁ states where no superscripts are used. [See Bist H. D. Brand J. C. D. , and Williams D.R. J. Mol. Spectry. 21, 76 (1966).]

The subscript e is used here with A and B to denote the A-and B-type bands in electronic spectra polarized in z (along the C—Cl bond) and y (perpendicular to C—Cl bond and in the plane of the molecule) directions, respectively. The C-type contours (with x polarization) are not observed in the spectrum.
