Abstract

Abstract: Volumes of activation (AF) and of reaction (AVO) have been determined by means of a laser apparatus with a high-pressure cell for the fast proton-transfer reaction between 4- nitrophenylnitromethane and 1, 1', 3, 3'-tetramethylguani-dine in five aprotic solvents (mesitylene, o-xylene, toluene, anisole, and chlorobenzene). The values of AVf* are around- 15 cm3 mol-'and do not vary by more than twice the standard deviations; those of AVO are ...
