Pico- and nano-second pulse radiolysis was applied to the study of the radiolysis of carbon tetrachloride (CCl4). In the u.v.-region, two different absorbing species were observed by using the twin linac pulse radiolysis technique. The component decays within 100 ps and the other component has a very long lifetime (about 100 ns). This long lifetime component has been reported in previous work. The absorption band of the very short lifetime component is broader than that of the long lifetime component in the u.v.-region. The growth of the absorption was measured very precisely using the twin linac pulse radiolysis and the analysis was carried out using the analytical solution of the Smoluchowski equation. Exponential function (R(r, r0) = (1/r0) exp (-r/r0)) as the initial distribution function of the geminate ion pair gives a better fit than the gaussian.
