Abstract

A water-cooled pulsed magnet having a room temperature bore of diameter 20  mm was constructed. Magnetic field effects on a triplet sensitization reaction of p -aminophenyl disulfide (APDS) with xanthone (Xn) were studied in a sodium dodecylsulfate (SDS) micellar solution by a nanosecond laser flash photolysis technique under ultrahigh magnetic fields of up to 28  T. Upon irradiation of the SDS micellar solution containing APDS and Xn, triplet radical pairs of p -aminophenylthiyl radicals were generated. The yield of the escaped p -aminophenylthiyl radical was found to decrease by 6  ±  2% at 28  T compared with that at 0  T. [ABSTRACT FROM AUTHOR]
