Rotational Constants of the Iodine Monochloride Molecule


Our analysis of the rotation structure of the iodine monochloride absorption bands is now sufficiently advanced to permit of a fairly precise determination of the molecular constants. The region 6482–6837 A. has been measured on plates taken in the second order of a 21 ft. concave grating, and practically all the lines have been allocated to series. The strongest bands in this region are σ″ = 1, σ′ = 8–12; some bands belonging to the σ″ = 0 and σ″ = 2 progressions are also present, and there are of course two complete systems, a strong one due to ICl35 and a weaker one due to ICl37. The figures given in the accompanying table refer to the former only.
