Chemical generator and EPR studies of the chemical-oxygen-iodine-laser system

Formation of O2 (supra 1 delta) by reaction of Cl2 gas with basic H2O2 liquid was studied using a small scale batch reactor. Effect on O2 (supra 1 delta) yield of certain reaction/reactor parameters were evaluated. Parameters included molarity of base and presence of Cl (-) initial reaction solution, use of Br2 as reactant, depth of Cl2 injector in solution area of cooled trap surface, and use of halocarbon coating on flow tube walls. Use of Cl2, base molarity, and trap conditions were areas in which greatest effects were observed. Mixture of argon and I2 were added to the flowing output from the generator and the high field (1.7 to 2.4T) EPR spectrum was scanned. No I2 or I species were observed. Values of g (sub exp) for two previously unreported EPR lines in the J=3 level of O2 (supra 1 delta) were obtained.
