Abstract
THE absorption spectrum of iodine monochloride consists of a group of bands (group Cl) with an upper convergence limit at about 17430 cm.-1 corresponding to the dissociation of ICl into a normal iodine atom and a chlorine atom in the 22P1 state. There is also another group (group I) of which only two members (17446 cm.-1 and 17570 cm.-1) were observed by Gibson and Ramsperger. Several further members of this group have since been observed (Gibson: unpublished measurements). These are visible in the region between the convergence and the absorption maximum of the continuum of group Cl.
