โœฆ Synopsis

By the study of the pressure dependence of the fluorescence and phosphorescence yields of pyrazinc vapors in the pressure range of 10-z-10 torr it wns established that the fluorescence decay is not exponential but contains a long component (7 = 10-6-10-7 set) corresponding to the "dilution" of the singlet radiative properties in the dense manifold of tripiet levels. The phosphorescence is due exclusively to the coilisionally induced rela;ation from the quasi-stationary state to the pure triplet state.

Fluorescence-excitation and quantum-yield spectra were measured along the rotational contours of the O-O and lOa: bands of pyrazme and the O-O band of pyrimidme in the vapor phase at low pressure. A marked variation in quantum yield was observed. The yield spectra for the O-O bands exhiiit a very sh
