Stimulated nuclear polarization (SNP) and time resolved electron spin resonance (TR ESR) spectra were recorded during the laser flash photolysis of [sup 13]C carbonyl labeled [alpha]-methyldeoxybenzoin solubilized in a series of alkyl sulfate micelles of different sizes. While the SNP spectra show a decrease in the splitting of the two hyperfine lines with decreasing micelle size, this decrease in hyperfine splitting is not seen in the experimental TR ESR spectra The qualitatively different variations between the SNP and TR ESR spectra, as a function of micelle size were interpreted in terms of the stochastic Liouville equation as applied to the model of the microreactor. 28 refs., 6 figs., 2 tabs.
