A syn-anti photoisomerisation of the carbon-nitrogen double bond is responsible for the photochromic properties observed with 2-arylhydrazones of 2-substituted 1,2-diketones.We have determined the multiplicity of the excited state involved in the process and we have shown that, in the thermal back-reaction, syn-anti isomerisation takes place through rotation around the C=N bond rather than through inversion of the nitrogen atom.
