✦ Synopsis


From a set of photochromic spiro[indoline-naphthoxazinesl substituted on the oxazine part, a correlation between the electronic charge of the 2'-carbon atom and the absorption wavenumbers of the corresponding coloured forms was found. This relationship is of particular interest to predict the colour developed by this class of photochromic compounds.
