Answer to Question #117305 in Physical Chemistry for Ayesha

Question

How wavelength effects the photochemistry of toluene.

Answer 1

spectrum of Toluene dissolved in cyclohexane. The excitation wavelength was 242nm. The quantum yield of this molecule is 0.17 (Berlman, 1971). This spectrum was collected by in the summer of 1995 using a Spex FluoroMax. The excitation and emission monochromators were set at 1 mm, giving a spectral bandwidth of 4.25 nm. The data interval was 0.5 nm and the integration time was 2.0 sec.
