Reversible photoisomerisation in molecular crystals may eventually become a new means of information storage. A certain loss of information can occur by thermal re-isomerisation. Furthermore thermal isomerisation is a reaction of type A → B other than a phase-transformation, which type has not often been studied so far. For these reasons we investigated the thermal cis → trans isomerisation of azobenzene.
