Fast Formation of Methyl Radical from Methylaquocobaloxime As Studied by Time-Resolved Optical and ESR Techniques Yoshio Sakaguchi: Hisaharu Hayashi,*-+and Yasumasa J. I'Hayat The Institute of Physical and Chemical Research, Wako, Saitama 351-01. Japan, and Department of Materials Science and Laboratory of Magneto- Electron Physics, The University of Electro- Communications, Chofu, Tokyo 182, Japan (Received: April 19, 1989; In Final Form: June 20, 1989) The photochemical primary processes of methylaquocobaloxime [CH3Co(CH3C(NOH)C(NO)CH,),(H20)] in water and 2-propanol were investigated with the aid of time-resolved optical and ESR techniques. The difference absorption signal between diaquocobaloxime and methylaquocobaloxime appeared immediately (
