摘要：
Temperature dependence of effective piezooptic coefficients pi-66(0), pi-12(0) for (N(C2H5)4)2ZnBr4 has been investigated. The spliting of phase transition near T2 under the influence of uniaxial mechanical strain sigma-6 has been established. It is supposed that this splitting is caused both by the change of ZnBr2-4 tetrahedron size and ordering of (N(C2H5)4)+ group.
