Measurements of the electrooptical Kerr effect of sulfur dioxide over a range of temperature ({approx} 299-490 K) and pressure ({approx}45-200 kPa) are reported. Analysis of the temperature dependence of the first Kerr virial coefficient in conjunction with the known mean polarizability and Rayleigh depolarization ratio yields high-precision values of the optical-frequency polarizabilities of the molecule. Results (10{sup 40}{alpha}{sub xx}/C m{sup 2} V{sup {minus}1}, etc., x direction perpendicular to molecular plane, y and z directions in plane, z coincident with C{sub 2} axis) emerge as 3.30 {plus minus} 0.04, 5.80 {plus minus} 0.06, and 3.88 {plus minus} 0.06 at 632.8 nm. The first and second Kerr hyperpolarizabilities make only very small contributions to the Kerr constant so that rather imprecise, but nevertheless valuable, estimates of these two properties are obtained.
