The spectrum of H 2 . The Bands analogous to the parhelium line spectrum. —Part II

Abstract

Errata in Part I . —On p. 70, line 22, the three values of 2α should read 1∙935, 1∙635 and 1∙465. These give an “average α” = 0∙839 which is identical with the value 0∙85 0 got in the other way. We now learn from a letter from Prof. Birge that this “constant” (the α in B n = B 0 —α n ) has the same value for the initial states of Dieke and Hopfield’s AB bands as for the final states of our systems. In Tables I and IX the intensity measures attributed to Kapuscinski and Eymers are not in many cases the values finally published by them. Their paper should be consulted if accurate values are required. The final values show an even better agreement with our classification than the preliminary ones.
