The change in fluorescence quantum yield for indole 2s a function of ercitition wavelengg between 250 and 220 run is found to vary with the static dielectric constant of various alcohol-\vater mixtures at 296 K. The supports rhe intermediacy of I CTTS sbte in tile photoionization process.
The fluorescence quantum yields of the 7-aminocoumti dyes coumarin 1,102,X3, LD490, and CSF were measured using argon, air, and osygen as cover gases. The results show that, in ethanol, oxygen does quench these dyes and that the fluorescence is signiiicantly improved in some coumarin dyes by the rem
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
