Abstract
AN investigation of the fine structure of the 2536 line of mercury has just been completed as a preliminary to the continuation of the work on the controlled orbital transfers of electrons in optically excited mercury vapour described recently in the Proceedings of the Royal Society. It has been found that the structure photographed by Prof. Nagaoka is not the true structure at all, but an absorption spectrum, or perhaps more exactly a structure caused by the self reversal of the true components, resulting from the circumstance that he worked with an Arons-Lummer type of lamp, in which the light of the arc is obliged to pass out through a column of non-luminous mercury vapour, before entering the interference spectroscope.
