    • For D-A polyenes, β can be maximized when there is an optimal degree of mixing between neutral and charge-separated canonical forms. As a function of increasing polarization, and starting from chromophores with weak D and A groups, β is positive, first increases, peaks in a positive sense, decreases, crosses through zero at the cyanine limit, and then becomes negative when the ground state of the molecule becomes zwitterionic. The rationalization of this behavior has allowed the establishment of very useful guidelines for the design of NLO chromophores. Molecules showing high positive (negative) β values with ground-states lying halfway between the neutral (zwitterionic) and the cyanine limit forms have been named left (right)-hand side chromophores
