The life times of chemically activated alcohols have been determined using the highβpressure unimolecular rate parameters for thermal decomposition of alcohols from shocktube studies and RRKM calculations. They are compared with literature numbers (from insertion of 0(^1^D) into hydrocarbons). It is suggested that in some cases singlet oxygen carries excess energy into the hydrocarbon. The consequences of such an assumption are explored and discrepancies with previously published conclusions discussed.

The use of alcohols as nucleophiles necessitates the consideration of further reaction pathways in addition to those discussed above, since, besides ketones and tautomeric enols, small equilibrium concentrations of enol ethers and acetals may also be present.['61 However, acetals and enol ethers nee
The RRKM theory and thz quantumraiation of RRK theory are used to c~lculare the decomposition rate constants of chemically activated CHFzCl and CHF,. The calculated values of the rate constants are compared with cxperimcntal datn. It is shown that the decompositions of CHFS and CHFzCt\* proceed muc
