The second-order hyperpolarizability (β) of pyridinium cations with cutoff (λco) shorter than 400 nm were studied by semiempirical calculation and the hyper-Rayleigh scattering (HRS) technique. The β value of 4-dimethylaminopyridinium (λco= 390 nm) was evaluated to be about 1.5 times larger than that of p-nitroaniline (λco= 473 nm) in methanolic solution using 1064 nm light as a fundamental beam.
