A large geometric distortion in the first photointermediate of rhodopsin, determined by double-quantum solid-state NMR
{{output}}
Double-quantum magic-angle-spinning NMR experiments were performed on 11,12-(13)C(2)-retinylidene-rhodopsin under illumination at low temperature, in order to characterize torsional angle changes at the C11-C12 photoisomerization site. The sample was illuminat... ...
