The gamma radiolyses of liquid alkanes with and without added iodine and methyl iodide or olefins were investigated. The systems and yields were: G(H/ sub 2/), G(CH/sub 4/), and G(HI) in cyclopertane, n-hexane, 3-methylpentane, and Z,4-dimethylpontane, each containing 2 x 10/sup -2/ M iodine and up to 0.8M methyl iodide; G(c-C/sub 5/H/sub 8/) and G(c-C/sub 5/H/sub 9/I) in cyclopentane methyl iodine; G(c-C/sub 6/H/sub 10/), G(c-C/sub 6/H/sub 11/I), and G(C/sub 12/H / sub 22/) in cyclohexane - methyl iodide - iodine; G (H/sub 2/), G(HD), and G(D/ sub 2/) for 1% cyclohexene-d/sub 10/ in cyclohexane and 1.5% cycyclohexene-d/sub 10/ in cyclopertane. Ultraviolet absorption of products was measured in vacuo for cyclohexane, cyclopertane, n-hexane, 0.05M cyclohexene in cyclohexane, and 0.05M cyclopentene in n-hexane at 20 deg C, and for 0.1M cyclohexene and 0.1M cyclopentene in 3-methylpentane glass at --196 deg C. The results are interpreted in terms of electron attachment and charge transfer as well as freeradical reactions. A yield of 0.5 molecule/100 ev or greater was found in cyclohexane for an organic product not previously reported. (auth)
