Raman Spectra of Benzene and Diphenyl

Raman spectrum of benzene.—By employing suitable filters with both mercury-arc and helium-arc excitation a number of new lines have been recorded. The complete spectrum given in frequency differences, $\Delta \nu$, is as follows: $\Delta \nu =606, 849, 992, 1178, 1584, 1603, 2460, 2542, 2597, 2617, 2784, 2928, 2947, 3046, 3060, 3164$. Anti-Stokes lines corresponding to $\Delta \nu$ values 606, 849, 992 are verified.
