Calculations are presented that show that vacancies can trap charge‐transfer (CT) states in anthracene, acetanilide and hexahydro‐1,3,5‐trinintro‐1,3,5‐triazine (RDX). Such trapping provides a mechanism for photoconductivity quenching by geminate recombination, and for optical damage and detonation by concentrating optical or mechanical energy stored in CT states.
