The static polarizability, and the static and dynamic hyperpolarizability of molecular hydrogen bonded complexes of nitropyridines with the hydrogen fluoride molecule and their ion pairs are investigated by ab initio Time Dependent Hartree Fock and Finite Field methods. The nonlinear electrooptical properties are calculated for a series of basis sets: 4-31G, 6-31G, 6-31G(d), 6-31G(d,p) and 6-311G(d,p). The calculated results show that the average value of the polarizability is almost independent of the form of the hydrogen bond, whereas a very large enhancement of the first and second hyperpolarizability due to proton transfer is found in the studied complexes.
