【 摘 要 】

On irradiation at liquid helium temperatures, rhodopsin is converted into hypsorhodopsin which decays to bathorhodopsin above 23 K. The absorption spectrum of cattle hypsorhodopsin (λ_max = 435 nm) is found to include a new sideband around 540 nm. This sideband may be due to π^* ← π transition to ¹A⁻ _g like state, which is made partially allowed by distortion of polyene chain of the retinylidene chromophore.
