Abstract
An important open question is understanding how the topography around a seam affects the dynamics of transitions between electronic states at CIs. This can be addressed by studying analogs of the visual pigment. In this work we compare the CI dynamics of rhodopsin with that of isorhodopsin, containing a 9-cis retinal which isomerizes around the 9=10 double bond and has a significantly lower quantum yield of only 0.22.
