Electron spin echo modulation and electron spin resonance of photoionized {omega}-phenothiazin-9-ylalkanesulfonate with alkyl + C{sub 3}H{sub 7}, C{sub 6}H{sub 13}, and C{sub 12}H{sub 25} (PC{sub n}S), 9-alkylphenothiazinesulfonate with alkyl = CH{sub 3} and C{sub 12}H{sub 25} (C{sub n}PS), and methylphenothiazine have been studied as a function of the surfactant alkyl chain length of sodium alkyl sulfate and alkytrimethylammonium bromide micellar solutions in D{sub 2}O, with alkyl = decyl, dodecyl and tetradecyl. Deuterium modulation effects from x-doxylstearic acid interactions with water deuteriums indicate that only the decyl surfactants form micelles with significant water penetration at the micellar interface.
