Unexpected halogen substituent effects on the complex thermal relaxation of naphthopyrans after UV irradiation

The kinetics of the thermal fading of four halogenated naphthopyrans (NP) have been analyzed using NMR spectroscopy in CD3CN. Two photomerocyanines (TT and TC) were detected after UV irradiation. The main relaxation process TC → NP was coupled
