In a recent paper [1] the writer has pointed out how the phenomena observed in the incoherent scattering of light by molecules can be easily accounted for with the quantum theory of dispersion. Kemble and Hill,[2] Langer [3] and Dieke [4] have independently developed similar considerations. The experimental results obtained by the writers, McLennan and McLeod, [6] and Wood [6] all support these theoretical conclusions. In the present paper I want to report some experiments which I have been carrying on recently, and which show the relationship between Raman transitions and band spectrum structure much more clearly than before. A preliminary communication of these results has already been given in a letter to Nature [1], but they were incomplete, and besides some inaccurate statements were made concerning the N2 spectrum. Recently Wood [6] seems to have obtained similar results on HCl, in which the separation of rotational levels is large enough to be resolved with the low dispersion employed. The essential improvement in the experimental arrangement consists in the use of the λ2536 mercury line as exciting light. The scattering is much stronger in that spectral region than in the visible, so that the Raman lines could be photographed with fairly large dispersion in a Hilger quartz spectrograph.
