Measurements were made of the quantum yields in the iodine-sensitized cis-trans isomerization of 1-phenyl-2-(1-naphthyl)-ethylene (PNE) and stilbene (STB) in n-hexane at room temperature over a wide range of variation of the exposure time, the concentrations of arylethylene and iodine, and the light intensity. The quantum yield in the iodine-photosensitized isomerization in a PNE melt was measured at 40/degree/C in a layer 15 /mu/m thick, and the analysis of the isomer composition was performed by subsequently dissolving the samples in n-hexane and measuring the absorption spectra of the respective solutions.
