Some photophysical and photochemical properties of 5H-dibenzo(a,d) cycloheptene have been measured including anti-Stokes scattering, prompt fluorescence, B-type of delayed fluorescence, phosphorescence and T1 - Tn absorption spectra. Quantum yield and decay parameters for the triplet state as a function of temperature have also been measured. The results are discussed and compared to those of molecules with similar structures and decay time of B-type fluorescence is reported here for the first time for dibenzocycloheptene. Stokes and anti-Stokes Raman scattering is observed on phosphorescence spectrum at 77K in methylcyclohexane.and anti-Stokes Raman scattering is observed very strongly on phosphorescence spectrum.
