Abstract:	Average structural characteristics of esters of benzoic acids have been found by statistical treatment of crystallographic data. A general procedure has been developed for determining electrooptical parameters that are optimal for a series of molecules with C_s symmetry. In a series of methyl benzoates p-R-C₆H₄-COOCH₃, the index ellipsoid of the unsubstituted molecule is characterized by semiaxes b₁=14.89, b₂=18.74, b₃=9.27 Å³; here, the b₂ axis deviates by 5° from the C-R axis.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 795–801, April, 1991.
