RESEARCH ON TRIPLET STATES AND PHOTOCHROMISM

Abstract

Research studies are described on the photochromic properties of the triplet states of aromatic compounds and their application to the problem of eye-protection against nuclear weapons. A Cary spectrophotometer has been specially modified to allow the transmission of a sample to be measured while it is under irradiation by a repetitively triggered flash lamp. Using this apparatus, triplet-triplet absorption spectra have been recorded for several new compounds in plastic media. Coronene, naphthocoronene and naphthochrysene are all found to have strong T-T absorption extending over most of the visible region.
