Abstract
Chiral molecules are inherently noncentrosymmetric, they posses an electric dipole allowed second order and higher even order optical nonlinearities. We show that multipolar contributions to the nonlinear polarization can be detected by using a method based on polarization chart of the second harmonic signal generated in a noncollinear configuration. Experiments have been performed on Bacteriorhodopsin protein (BR) oriented multilayer film. © 2011 ACM.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
