Keep 'em separated: Stereoisomers of complex molecules generally have very different electric dipole moments for the same mass. The different dipole-moment-to-mass ratios can be exploited in the separation of these species using electric fields. The pure samples thus created offer opportunities in isomer-specific and stereoselective investigations.
