✦ Synopsis

A novel method for detecting changes m chemxals, especially radical formation after ultraviolet (UV) lrradlatlon, was developed usmg lmlpramme as a marker of hght-sensitive materials The system consisted of a pump, an mJectlon port for the sample, an on-hne UV irradiation device and detectors for chemdummescence and electron spm resonance (ESR) Most chemicals that were chemdummescence posltlve after UV nradlatlon m this flow system were found to show spectra of free radicals by ESR spectroscopy These results suggested that the proposed on-line system may be useful for the rapld and simple detennmatlon of the stab&y and light-induced degradation of chemicals

## Abstract PVA films with various filling levels of CrF~3~ and MnCl~2~ were prepared. ESR and UV/VIS optical analysis were used to shed more light on the structural modification that occur due to filling with different levels and/or UV irradiation. The ESR analysis revealed that the spin configura
