The first excited singlet state S1 of trans-thioindigo has been investigated mainly by fluorescence emission, excitation and lifetime measurements in various solvents over a wide temperature range. The experimental results are interpreted in terms of a dual luminescence model, which arises from the ...

Photosensitised generation of singlet oxygen, O2*(a1Δg), in supercritical xenon, SCF-Xe at 325 K is reported for the first time. Rate constants for quenching by ground state oxygen, and by xenon, vary from 8.9±0.3 to 13±1×102 and fro... Ayman,A.,Abdel-Shafi,... - 《Chemical ...

Stern–Volmer plots for the quenching of the first excited singlet states of a variety of substituted benzenes by molecular oxygen in the vapour phase are presented and fluorescence decay times measured, yielding quenching rate constants. These values are shown to vary only slightly from compound to...
The polarizability of tetracene in the first excited singlet state relative to the ground state has been determined from electro-optical studies of the first absorption band of tetracene in benzene solution. The theory of electro-optical effects for nonpolar molecules is reformulated and for ...
According to \(\Delta S\) = 0, optical transition rule, the first triplet excited state is optically inactive, therefore, the lowest excitation energy transfers the ground state, point A in Fig. 10, into the first singlet excited state, point B in Fig. 10, with the creation of an excit...
