Electronic Spectra of Various Liquids under Shock Conditions.

Abstract

A series of experiments is described in which the time resolve spectra of several liquids have been recorded as they were compressed by shock waves reverberating between two sapphire plates. The extent of chemical reaction is reported as indicated by red shift of the uppermost absorption band in the UV or visible. Most of the liquids were organic materials containing 0,1 or 2 carbon double bonds. Unsaturated substances are, on the whole, more reactive than saturated ones, but the relation is not simple. One of the few inorganics studied was HI, which reacted very rapidly an in two stages. Some comments on possible mechanism are included, along with cautions about the interpretation of this kind of experiment. Keywords: Dynamic compression; Shock chemistry; Fast reactions; Unsaturated hydrocarbons; Nitromethane; Styrene; CS2; Spectroscopy; Condensed matter.
