title: Atomic and molecular parity nonconservation and sum frequency generation solutions to the ozma problem.
abstract: Two Ozma problems are defined. Parity nonconservation is necessary for their solutions. Both problems may be solved by beta decay or atomic optical activity. Atomic and molecular sum frequency generation is chosen, as it supplies rich methods of effecting "gedanken" solutions to the Ozma problems. A new method of measuring a parameter manifesting molecular parity violations is advanced.
