Molecules of the kind described would be chiral in the electronic ground state but would racemize in the presence of light as a result of electronic absorption and subsequent emission, with equal probability, to either enantiomer. Professor Albert Moscowitz, University of Minnesota, suggested two systems that have been shown to exhibit photoracemization without bond breaking and would therefore be candidates for experiments of the kind proposed here. One is a biphenyl derivative whose photochemical behavior was reported by

proposed an experiment for measuring the small energy difference between two enantiomers due to parity-violating weak neutral currents. The proposal was for quasicontinuous-wave optical pumping of parity eigenstates in isolated handed molecules with planar (i.e., achiral) excited electronic states and the additional feature that the parity violating perturbation greatly exceeds the ground state tunnel splitting. It was shown to be possible, at least in principle, to observe coherent interconversion, on the timescale of hours, between parity eigenstates in the electronic ground state

2 have verified the dependence of the response to a delayed pulse on the relative optical phase with the initial pulse by direct measurement of the delayed pulse forward scattering amplitude. See J. N. Sweetser, T, J. Dunn, and I. A. Walmsley (preprint, March 1993). For a detailed investigation of the possible use of optical phase-controlled pulse sequences to measure electronic geometric phase development in Jahn-Teller active molecules, see
