Stokes and anti-Stokes Raman scattering of 5H-dibenzo(a,d)cyclohepten-5-ol

The ultraviolet absorption and emissions as well as Stokes and anti-Stokes Raman scatterings of spectroscopically pure 5H-dibenzo(a,d)cycloheptene-5-ol were investigated by flash and laser-flash photolysis technique in solution at room temperature and at 77 K. The whole spectrum, absorption, excitation, prompt and delayed fluorescence, T–T absorption spectra were recorded photographically and photoelectrically in the ultraviolet and visible region and phosphorescence spectrum, Stokes, anti-Stokes scatterings were recorded at 77 K.
