DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Turning on the ring current: p Electrons in a chiral arom. mol., such as dichloro(3,6)pyrazinophanes (see scheme), can be rotated along the arom. ring by linearly polarized laser pulses. 19745-07-4 which is the cas registry number of some chemical is mentioned. Selective generation of an (approx.) angular momentum eigenstate consisting of optically allowed, quasi-degenerate p-electronic excited states is responsible for the rotation. The direction of the photoinduced ring current is controllable in each enantiomer. .
