Abstract

Abstract An abrupt change of some Bragg reflections occurs near the neutral-ionic transition temperature(TN-I) in TTF-chloranil. We performed intensity analyses of (3 k l) Bragg refrections below TN-I and found that donor (TTF+:D) and acceptor (chloranil−:A) molecules form D-A dimers below TN-I
