The second hyperpolarizability (γ) of carbon tetrachloride was measured by gas-phase electric-field-induced second-harmonic generation (ESHG). Periodic phase matching was used in order to enhance the ESHG by gases illuminated by a cw argon-ion laser operating at 514.5 nm. Using nitrogen as a reference gas, γCCl4 can be calculated by means of the ratio γCCl4/ γ N2 determined to be 18.3 ± 0.7.
