| Abstract: | The use of geometrical isomerization of stilbene as a monitor of radiolytic excitation in methanolic solutions was evaluated using gas chromatographic analysis. No evidence for excitation of stilbene was obtained. The mechanistic significance of the observed isomerization of trans-stilbene is obscured by the preponderant simultaneous formation of a veriety of other products. The cis-stilbene used in this work was much less sensitive to ionizing radiation than its trans-isomer, presumably because of efficient protection by a few percent of 2-methylnaphthalene present as an impurity. |
