In order to understand the different phenomena that exist between light interaction and organic or inorganic molecules, this article describes, in general, the processes that a molecule can follow when excited by light radiation. This, in turn, helps to interpret phenomena observed in a laboratory, or something closer to us, such as nature. To make this description, we analyze the existing classifications of these mechanisms. The interaction of light can be established through different processes: photophysical, photochemical, radiative, and non-radiative. Thus, the classification will depend on the type of molecule and the nature of the chemical bonds (connections). For this reason, this article focuses on describing such processes, exemplifying the phenomena to which they relate. The aim is that the reader can obtain a general understanding of the different mechanisms of light and molecules interaction.
