Abstract
ONE of the major products in, alkyl iodide photolysis in various solvents is iodine, formed by combination of iodine atoms produced in the primary dissociation. Although the reaction is well known, quantum yields reported for iodine vary from zero to one1–6. In part, the scatter in the data from different laboratories is caused by the presence of undetermined amounts of oxygen. Hacobian and Iredale6 pointed out the difficulty of complete removal of oxygen from these solutions in organic solvents, and found that the iodine yield decreased from 0.5 to less than 0.05 as the solution was degassed. Earlier work1,5 indicated a decrease of about a factor of two in iodine-yield on removal of oxygen.
