H. Koizumi et al., RADICAL FORMATION IN PULSE-RADIOLYSIS OF ORGANIC SOLUTIONS OF 9,10-DIHYDROPHENANTHRENE, Radiation physics and chemistry, 50(6), 1997, pp. 567-573
Formation and decay of neutral radicals from 9,10-dihydrophenanthrene
(DHPT) in irradiated organic solutions was studied by pulse radiolysis
method. Major species of the neutral radicals are H-adducts (H-DHPT)
in ethanol solution of DHPT, whereas they are 9-hydrophenanthryl radic
als (9-HPT) in 1,2-dichloroethane(DCE) solution of DHPT. In ethanol so
lution, H-DHPT is generated through proton transfer to the anion radic
al of DHPT and through reaction between atomic hydrogen and DHPT. In t
he DCE solution, 9-HPT is generated mainly through deprotonation from
cation radicals of DHPT. Reaction between solvent radicals and DHPT pl
ays a minor role fbr the formation of 9-HPT. (C) 1997 Published by Els
