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
