| Popis: | Phototransformations of 1,8-dicarboxyisobutyl-substituted p-terphenyl in ethanol are studied upon excitation by a XeCl laser at a power density of up to 180 MW/cm2 for different types of radiation and different excitation geometries. The absorption and emission spectra are studied before and after irradiation. The resources of the lasing medium, quantum yields of phototransformations, and relative quantum yields of photoproducts are determined. The transmission of the solutions at the excitation wavelength and the shape of radiation pulses are measured as functions of the pump power density. |
