The Tesla-Luminescent Spectrum of Benzene

Abstract

IN a recent letter to NATURE (Sept. 7, 1929), Shapiro has pointed out that Riemann's wave numbers for the fluorescence spectrum of benzene (Ann. d. Phys. 80, 43; 1926) could be expressed by formulæ of the type ν = 37494 + 921n′ − 998n₁″ − b n₂″ where b takes the values 0, 600, 855, and 1180 in four series and n′, n₁″, and n₂″ have appropriate small integral values.
