The triplet–triplet absorption spectra of several phenylnaphthalenes are measured and the absolute extinction coefficients are evaluated using the simultaneous ESR–optical approach. The results of self-consistent-field molecular-orbital calculations are compared with experiment and good agreement is found for the energies, oscillator strengths, and vibrational envelopes of the triplet–triplet transitions. In addition, the angles of polarization of the triplet–triplet transitions are predicted, and their significance in the interpretation of triplet-state structures is discussed.
