Abstract
THE coarse spectrum of copper iodide in the visible region was investigated by Mulliken1 in 1925 and Ritschl2 in 1927. Ritschl recorded five extensive band systems in absorption, all degraded to red in the region 3750–5500 Å. From a study of their vibrational analysis he concluded that all systems have a common lower state which is the ground state of the molecule. This communication reports the results of the rotational analysis of the E–X bands of 63Cu127I.
