The radical cation of octaisopropylcycloletragermane, ((Pr2Ge)-Pr-i)(4), ge
nerated by the pulse radiolysis technique showed two transient absorption b
ands at 305 and 435 nm. These transient peaks were quenched with diphenylam
ine and triphenylamine as radical cation scavengers. (C) 1999 Elsevier Scie
