Abstract
To account for the influence of temperature on rates and levels of conductance in basic fuchsin, two activation energies are required; for diffusivity and for quantum yield of charge carriers, and these are approximately equal having a value near 0.38 ev. Two regimes of behavior with respect to light intensity are found, one in which the response is proportional to the illumination, and another, which may be established by strong pre-illumination of the film, in which the response is as the square root of the light intensity. These observations are in accord with the hypothesis which was proposed to account for the inverse dependence of rate constant on initial conductance in crystal violet.
