Journal of Applied Spectroscopy Aims and scope

Abstract

The quasiline spectra of the fluorescence and absorption of bisanthene in n-hexane are obtained at 77 and 4.2 K, and their vibration analysis is carried out. Substantial violation of the mirror symmetry of the fluorescence and S1 ← S0-absorption bands with respect to both the frequencies and intensities is found. This allowed the conclusion that the S2-level is localized in the region of vibronic sublevels of the S1-state with\(\Delta E_{S_2 S_1 } = 1395 cm^{ - 1} \).
