Table 3.

The energies of the (0-0) and (0–1) vibronic bands of the cis-peak, S0 (11Ag −) → S3 (11Ag +) transition, in the UV region of the steady-state absorption spectra. Also given are the energies of the small long wavelength bands in the third EADS components summed with the S1 (21Ag −) energies of the central-cis isomers of the xanthophylls and β-carotene. All values are given in cm−1.
