The membrane protein bacteriorhodopsin is a proton pump, in which proton transport is initiated by the light-induced isomerization of the chromophore retinal. The molecular quantum states involved in ...
A new, ultrafast raman spectroscopy method has given researchers a glimpse of the early stages of the vision process. Vision is jump-started by the isomerization of the retinal chromophore in ...
ONE LITTLE BOND—the double bond—is beginning to make a big difference in neuroscience. Under the right chemical circumstances, double-bonded compounds can respond to light by converting between trans ...
