COVER Three-dimensional Wigner plot (where x is time, y is wavelength, and z is amplitude of the electrical field) of the specific laser pulse found to enhance the photoisomerization quantum yield of retinal in bacteriorhodopsin in the weak excitation limit. The complex periodic pattern induces coherent nuclear motions that are specific to the isomerization reaction. See page 1257. Image: Helena V. Prokhorenko
