Abstract
We have studied chiral nonlinear optic (NLO) effect in a bent-core molecular system. Particular attention has been paid to the second-order NLO process involving the magnetic dipole transition process. As one of the examples, second-harmonic generation circular difference (SHG-CD) is observed in two chiral domains in the B4 phase of a mixture of P-8-OPIMB/P-8-OPIMB6∗. The signs of SHG-CD are different and the absolute values are the same in the two domains.
