โœฆ Synopsis

The effect of solvent polarity on the position of the absorption band of photochromic compounds from the benzothiazoline spirobenzopyran group is investigated.

The possibility of formation of in&a-and intermolecular hydrogen bonding is also discussed. The experimental results obtained show that even in the ground state in media of lowpolaritythecoloured molecules of themerocyanine structure have a predominantly zwitterionic structure.

Proton spin-spin relaxation time measurements have been performed at 300 and 400 MHz on bound rubber-filler mixes resulting from the solvent extraction of silica-filled and silicafilled-modified polybutadiene, on the one hand, and of carbon black-filled and carbon blackfilled-modified styrene butadi
