title: Spectroscopic studies on the photoeffects on some metallocenes in the presence of chloroform molecules confined in poly(methyl methacrylate) thin films.
abstract: The changes in the electronic absorption spectra (UV-Vis) (after photoexcitation) of poly(methyl methacrylate) (PMMA) thin films doped with a metallocene and containing chloroform molecules as impurities, have been studied as a function of photoexcitation wavelength (210-750 nm), photoexcitation time (duration), amount of metallocene in the film and amount of chloroform molecules present in the film. Photoeffects on the metallocenes have been observed, which depend significantly on the nature of the central metal atom of the metallocene and the results have been discussed on the basis of the electronic configuration of the metallocenes, which is under study.
