    • The laser system uses Lumonics EX-510 and EX-530 for excitation wavelengths of 248 and 308 nm, Surelite lasers from Continuum for the Nd-YAG wavelengths of 266, 355, and 532 nm and a Molectron UV-24 nitrogen laser for 337 nm. All pulse durations are <10 ns, and typical pulse energies, between 5 and 50 mJ. The signals from the monochromator/photomultiplier system were initially captured by a Tektronix 2440 digitizer and transferred to a PowerMacintosh computer that controlled the experiment with software developed in the LabVIEW 3.1.1 environment from National Instruments. Other aspects of the system are similar to those described earlier: Scaiano, J. C. J. Am. Chem. Soc. 1980, 102, 7747. Scaiano, J. C.; Tanner, M.; Weir, D. J. Am. Chem. Soc. 1985, 107, 4396.

    • It will eventually be desirable to obtain kinetic data at typical polymerization temperatures (90-130°C), for example in toluene, a solvent frequently chosen for nitroxidemediated polymerizations.

    • note
    • CSA causes a decrease in the quantum yield of photodecomposition of I; the observation was not pursued further, since in practice cleavage of the C-TEMPO bond is done thermally.
