Abstract
IN the course of a systematic study of the excitation of selenium vapour in a high-frequency discharge, we have observed, on the short wave side of the main 1–1 system1, a new system of about forty weak and diffuse bands degraded to the red which may be approximately represented by the following formula: These bands appear at low temperatures, before the main system becomes visible; but when the temperature is raised, the main system becomes incomparably more intensified than the new one.
