    Quenching of Pyrene Sulphonate Fluorescence in Inverse Micelles
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1977, 73 (10), 1977) Miller, Dennis J; Klein, Uwe K. A; Hauser, Manfred
    The fluorescence of 1-pyrene sodium sulphonate solubilised in benzene solutions of cetylbenzyl-dimethylammonium chloride/bromide is quenched by the bromide. The quenching constant is not markedly affected by the addition of water, which hardly dilutes the ionic layer.

    Quenching and Isomerization in the Photolysis of trans-But-2-ene and cis-Pent-2-ene at 185 nm and 203 nm
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (2), 1972) Borrell, Peter; Cervenka, A
    Additional results on the effect of additives on the product yields in the vapour-phase photolysis of trans-but-2-ene and cis-pent-2-ene are reported. They confirm, extend and reconcile our previous results with those of Chesick. The main photoreaction could be quenched by all additives at both wavelengths; at 203 nm, and with some additives at 185 nm, quenching was accompanied by photoisomerization. The effects can be correlated with the two states, Rydberg and V(π→π*), which are excited at the two wavelengths. Collisional deactivation of the V state results in photoisomerization while when the R state is deactivated no isomerization occurs. Apparently there is no ready collisional interconversion of the R and V states.

    Photochemistry of 1,3-Dichloro-tetrafluoroacetone: Part 3.—Quenching of the Excited States
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (2), 1972) Hackett, Peter A.; Phillips, David
    The quenching of the excited singlet and triplet states of 1,3-dichloro-tctrafluoroacctone by various molecules is reported. Correlation of results with decomposition data indicate that for 310 nm excitation, some 25-30 % of the decomposition products arise from the singlet state, the remainder from the triplet state. The various mechanisms by which the excited states are quenched by different molecules arc discussed, and rate-constant data compared with that for hcxafluoroacctonc
