%X Experimental dipole moments and infinite-dilution molar Kerr constants are reported for six p-substituted acetophenones (CH3COC6H4X; X = Me, But, NO2, CN, F, Br) as solutes in carbon tetrachloride at 298 K. Analysis of these results and reconsideration of previously reported data for acetophenone and p-chloroacetophenone yields the dihedral angle, &#934;, between the planes of the carbonyl and aryl groups in the effective conformation of each molecule (X = H, &#934; = 0&#176;; Me, 0&#176;; But, 10±10&#176;; NO2, 20±15&#176;; NO2, 20±20&#176;; F, 27±5&#176;; Cl, 32±5&#176;; Br, 30±10&#176;).
