Conference paper


It has been known for about ten years that when frozen solutions (glasses) of visual pigments at 77°K are illuminated with visible light, there are changes in the absorption spectrum of the pigments (1, 2, 3). These changes in the absorption spectrum, which in general are fairly small (less than 20 nm shifts in the absorption maxima), are dependent on the wavelength of the illuminating light and show the typical behavior of the photochromic systems.
