Abstract
The first hyperpolarizabilities of some symmetrically substituted tria zines have been measured and compared with those of the corresponding symmetrically substituted benzenes. The octupolar triazines have highe r quadratic polarizabilities than the corresponding octupolar benzenes . The triazine ring seems to be a better central acceptor than the ben zene ring, but if it acts as a donor as in sym-triphenyl triazine, the nonlinearity improves further.
