The phenomenon of bioluminescence has fascinated layman and scientist alike for many centuries. During the eighteenth and nineteenth centuries a number of observations were reported on the physiology of bioluminescence in Renilla, the common sea pansy. More recently biochemists have directed their attention to the molecular basis of luminosity in this colonial form. These studies have centered primarily on defining the chemical basis for bioluminescence and its control. It is now established that bioluminescence in Renilla arises due to the luciferase-catalyzed oxidation of luciferin. This results in the creation of a product (oxyluciferin) in an electronic excited state. The transition of oxyluciferin from its excited state to the ground state leads to light emission.

Shift Dynamics

The ground and excited state evolution of fingerprint vibrational modes of all-trans-and 13-cis-retinal are mapped by impulsive vibrational spectroscopy. All-trans-retinal shows slower frequency shift dynamics in the excited state in comparison to 13-cis-retinal.
