Abstract
LONDON. Royal Society,1 June 21.—E. S. Semmens: The selective photo-chemical action of polarised light (Part 3). Well-washed potato starch grains, in distilled water, disintegrate under the influence of a Tyndall beam of light, polarised by the colloidal particles of diastase, contained in an outer vessel. The stages of hydrolysis bear a strong resemblance to those formed under ordinary diastatic action, suggesting that the polarisation of the incident radiation of heat or light is an important factor in the action of colloidal catalysts. As catalytic action takes place at surfaces, the possibility of some correlation between the constant plane of vibration of the radiation and the definitely orientated force fields or electron orbits of the molecular surface layers is indicated.
