= Photolysis coefficient
{synonym}

The first-order rate coefficient for a specified <photodissociation> channel. It integrates spectral <actinic flux>, absorption <cross section> and channel <quantum yield>. Absorption without dissociation does not contribute to that channel's rate. Its units are inverse time.
