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.
胆红素的高光敏性是新生儿黄疸采用光照治疗的主要原因。激发态胆红素的弛豫过程似乎受尚未完全明确的复杂机制所支配。在室温下，无辐射通道，如Z----E构型光异构化和内转换，在单线态激发胆红素的失活过程中起主要作用。构成该分子的两个次卟啉酮发色团之间的激子耦合过程可能在胆红素光物理过程中起关键作用。
