Rhodopsin is the pigment in the retina rod cells
responsible for vision, and it consists of a protein
and the co-factor retinal. Retinal is a T-conjugated
molecule which absorbs light in the blue-green
region of the visible spectrum, where photon
absorption represents the first step in the visual
process. Absorption of a photon results in retinal
undergoing a transition from the ground- or lowest-
energy state of the molecule to the first electronic
excited state. Therefore, the wavelength of light
absorbed by rhodopsin provides a measure of the
ground and excited-state energy gap.
