โฆ Synopsis
The high photosensibility of bilirubin represents the main reason why neonatal jaundice is treated with light. The relaxation processes of excited bilirubin appear to be governed by complex mechanisms which are not fully known. At room temperature, radiationless channels, such as Z----E configurational photoisomerizations and internal conversions, contribute mostly to the deactivation of singlet excited bilirubin. Exciton coupling processes between the two pyrromethenone chromophores constituting the molecule may play a crucial role in bilirubin photophysics.

In invertebrate visual cells, the rhodopsin content is maintained at a high level by the fast process of photoregeneration during daylight. Rhodopsin is converted by photoabsorption to metarhodopsin, which is reconverted to rhodopsin by light. In addition, rhodopsin is regenerated by a slow process
