The build-up of triplet-triplet absorption at 430 nm has been measured by the picosecond spectroscopy method. The rate constant For the build-up of the T1 state in iso+ctane was determined to bc 8 X lOLo s-l \_ The fast intersystem crossing indicates the presence of the Tg(mr\*) state below S1\_ 1.
