Luminescence of 5-Phenyltetrazole and its Derivatives Part III. Quantum Yields and Mean Lifetimes of Fluorescence
Keyword(s):
The Mean
◽
Abstract Quantum yields and mean lifetimes of fluorescence have been measured of 5-phenyltetrazole and its three methyl derivatives, para-, meta- and ortho-methyl-5-phenyltetrazole. The rate constants, kF, of the radiative transition S1 → S0 have been deduced from these measurements. The mean lifetimes, τF, the quantum yields of fluorescence and the rate constants have been found to be clearly dependent on the position of the methyl substituent in the ring and could be arranged as follows:τpF>τmF>τ0F and k0F>kmF>kpF
