Abstract
THE analysis of the spectrum of the normal iodine atom has proved relatively difficult, partly because of the wide multiplet separations, and partly because of the transitional nature of the coupling characteristics. Some constant intervals, due to Turner1, have long been known, and S. F. Evans2 in 1931 presented a partial analysis which included most of the stronger lines in the region 4700–10000 A. Recently S. C. Deb3 has published a more extensive analysis, which differs very materially from that of Evans. As he dismisses the ,latter's results rather summarily, with the remark that they are “mainly incorrect”, some observations on his paper may be of assistance in forming a just appreciation of the present position in regard to this question.
