Assignments of several groups of iodine (I 2) lines in the B- X system

Abstract

The spectra obtained by means of Fourier spectroscopy and the assignments of the B- X lines of I 2 in the vicinity of two argon ion laser lines (5145 and 5287 Å), three krypton ion laser lines (5208, 5308, and 5683 Å), and one HeNe laser line (6119 Å) are given. A detailed comparison, in the vicinity of the argon ion laser line (5145 Å), between the iodine wavenumbers calculated by means of the two sets of molecular constants previously published [Wei and Tellinghuisen, J. Mol. Spectrosc. 50, 317–332 (1974); Barrow and Yee, J. C. S. Faraday II. 69, 684–700 (1973)] with those calculated from Fourier spectroscopy data, is presented.
