Abstract
The molecular first hyperpolarizability (beta) of a series of benzoate anions and their esters were measured by the hyper-Rayleigh scatterin g (HRS) in methanol solution. The effect of the presence of methanolic solvation on their beta values were calculated and clearly correlates to the experimental beta. The static beta values of some of the benzo ate anions were evaluated and found to be close to those of pNA irresp ective of the cutoff wavelengths being shorter than 400 nm, and the ab sorption maximum shorter than those of corresponding esters. These new anions would be promising starting compounds for ionic crystalline se cond-harmonic generation (SHG) material of diode laser.
