Firefly luciferase catalyzes a light‐emitting reaction in which an excited‐state product is formed. Both experimental and theoretical methodologies are used to study this system, and the reactions catalyzed by luciferase are relatively well characterized. However, the mechanism by which an excited‐state product is formed is still unknown.

Isolated firefly does not receive stimulus from any other firefly in the network, and it is flashing with a period of time of seconds. If a firefly blinks with a certain period, we take on the sequence of flashes as a circular unitary motion; see figure 1 where the angular position is a point in the unitary circle and a short flash or pulse.
To this end we have used a computational approach to study the fluorescence quenching of firefly luciferin, the most studied member of the oxyluciferin family of fluorophores. We have found that the fluorescence quenching is due to the excited state protonation of the nitrogen heteroatom of the benzothiazole moiety.
