Organic Materials for Nonlinear Optics and Photonics

As a result of its discussions the working party suggest that the following areas of theoritical work, or of experimental work related to theoretical developments, should be pursued and would be likely to lead to a better understanding of the behaviour of organic materials in nonlinear optics and also to new developments of practical importance: (1) Foundations of the theory of the Hyperpolarizabilities of Long, Linear Conjugated Molecules.
