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
Fluorescence intensities and lifetimes of 1, I '-diethyl-2,2'-cyanine chloride( pseudoisocyanine) at I .O x 1 O-\* M in glycerol have been measured in the temperature range 84-298 K. Comparison with previous results shows that the solution consists of dye monomers. Arrhenius plots yield two activat
