Solvent can dominate optical rotation

Department: Science & Technology

The three-dimensional arrangement of achiral solvent molecules surrounding chiral solute molecules has been shown to make an unexpectedly large contribution to the optical properties of the solution. Achiral solvents are known to affect the experimentally measured optical rotation of chiral solutes, but the magnitude and fundamental nature of such effects were unknown until now. David N. Beratan of Duke University, Peter Wipf of the University of Pittsburgh, and coworkers find that the optical . . .
