%X Consideration of molar Kerr constants, dielectric polarizations, etc., now found for azoethane and azoisopropane as solutes in benzene, leads to the conclusions that the polarizability ellipsoid for the N=N group has semi-axes (in 10-23 C.O. units) as follow: bLN:N = 0.285, bTN:N = 0.100, and bVN:N = 0.079. No photo-isomerism can be recognized with azoisopropane analogous to that which is well known with azo-aryls.
