The refractive indices recorded in the preceding paper were determined in order to prepare the way for an attack, which is still in progress, on the problem of optical exaltation in compounds containing conjugated double bonds. They have, however, an immediate value in that, when combined with the refractive indices ofcyclo hexane, they can be used to determine the refractivities over a wide range of wave-lengths of the three radicals O >O, >C=O, and —C⋜ O—. The formulæ of the compounds in question are set out below:—Refractivities of O, CO,and CO2 (i) In order to deduce the refractivity of theoxygen radical it is only necessary to subtract the refractivity ofcyclo hexane from that ofcyclo hexanol, since these two compounds differ only by a single oxygen atom. R [C6 H11 OH] - R [C6 H12 ] = R [O].
