Abstract:
The intensities of the vibrationally induced bands in the S1---S0 emission and absorption spectra of pyrene-h10 and -d10 are measured and analysed. Several new expressions are reported which relate the deuterium effect and emission—absorption asymmetry of induced spectra to the vibronic coupling mechanism.
