✦ Synopsis

I-he 4-(trimethyl tin)butyI-2 radical. prepared and excited by the chemical activation reaction of H atoms with 4-(trimethyl tin)butcne-1. was found to randomize its excess internal vibrational energy on a subpicosecond time scale, This result differs from an earlier study on the decomposition of 3-(trialIyl tin)-2-ff~~ropropyl radical in which heavy-atom blocking of internal relaxation was reported.

The possibility that a heavy atom can block internal ener,gy transfer in excited species has been further investigated by chemical activation study of 4Xtrimethyl lead)-2-butyl and S-(trimethyl tin)-Z-pentyi radicals. These radicals were prepared and excited by the reaction of H atoms with the corre
