Some of double salts derived from ethylenediamine (en) and a variety of trans-cinnamic acids and their analogs underwent photodimerization in the solid state, giving predominantly β-truxinic dimers. X-Ray studies demonstrate that (a) the conformation of en is gauche for the highly photoreactive double salts (o-1b·en and m-le·en), whereas it is anti for lessphotoreactive o-la·en or photoinert Id·en and (b) for highly reactive o-lb·en and m-le·en, the monomer acid molecules are arranged in an overlap configuration and a reactive monomer pair is hydrogendashbonded to the same en molecule.

The techniques of infrared and Raman microscopy have been used to monitor the photochemical dimerisation reactions of β-2-chloro-trans-cinnamic acid, β-3-chloro-trans-cinnamic acid, β-4-chloro-trans-cinnamic acid, α-2-methoxy-trans-cinnamic acid, β-2-nitro-trans-cinnamic acid, β-3-nitro-trans-cinnamic acid and β-4-nitro-trans-cinnamic acid. In this way the topotactic nature of the reactions has been confirmed. These reactive derivatives have been compared with the unreactive γ-forms of these and related compounds.
