Wavepacket splitting and two-pathway deactivation in the photoexcited visual pigment isorhodopsin.

Abstract:

Isorhodopsin is the visual pigment analogue of rhodopsin. It shares the same opsin environment but it embeds 9-cis retinal instead of 11-cis. Its photoisomerization is three times slower and less effective. The mechanistic rationale behind this observation is revealed by combining high-level quantum-mechanical/molecular-mechanical simulations with ultrafast optical spectroscopy with sub-20 fs time resolution and spectral coverage extended to the near-infrared. Whereas in rhodopsin the photoex...
