Mercury-sensitized luminescence of alcohols
C. G. Freeman, M. J. McEwan, R. F. C. Claridge and L. F. Phillips
Rate constants for quenching 253.7 nm fluorescence, and quantum efficiencies for emission of luminescence during mercury-sensitized photolysis have been measured for methanol, ethanol, propanol, isopropanol, n-butanol, isobutanol, sec-butanol, tert-butanol and tert-amyl alcohol. From the variation of luminescent efficiency with the structure of the alcohol it is concluded that the main process competing with luminescence is normally the abstraction of an
-hydrogen by a metastable Hg(3P0) atom formed during quenching of Hg(3P1). For tert-butanol and tert-amyl alcohol the rate constants for reaction with Hg(3P0) are (7.5 ± 2.5)× 10–12 and (2.2 ± 0.8)× 10–11 cm3 molecule–1s–1 respectively; lower limits are given for the rates of reaction of the other alcohols with Hg(3P0).
