WebMay 24, 2024 · A photochemical reaction is a chemical reaction that is initiated when the molecules of a substance absorb light energy. This reaction causes the molecules to undergo a transient excited state, consequently changing their physical and chemical properties from the original molecule of the substance. When this occurs, these … WebJun 1, 2016 · 1. Introduction. Photochemistry, the study of the physical and chemical fates of polyatomic molecules excited electronically by the absorption of ultraviolet, visible and in some cases, near-infrared light was until the 1960s a phenomeno- logical subject only, because absolute rates of decay of the electronically excited states of molecules first …

What is a Photochemical Reaction? - Definition from

Webphotochemical: [adjective] of, relating to, or resulting from the chemical action of radiant energy and especially light. WebThis definition supposes that all the incident light is either transmitted or absorbed, reflection or scattering being negligible. Tradition-ally (spectral)radiant intensity, I, was used instead of spectral radiant power, P, which is now the accepted form. (The terms: absorbancy, extinction, and optical density should no longer be used.) Webphotochemistry: [noun] a branch of chemistry that deals with the effect of radiant energy in producing chemical changes. deutsche bank service mail
