an in extenso analysis of the (b-x)i//2 iodine absorption spectrum recorded by means of fourier transform spectroscopy is presented. it is shown that the 100 000 recorded transitions covering the 11 000-20 040 cm** $minus$ **1 range and published in several atlases may be recalculated by means of only 46 constants: 45 are dunham coefficients describing the vibrational and rotational constants of both x state (up to v** $double prime$ $equals$ 19) and b state (up to v** $prime$ $equals$ 80, situated only at 1. 6 cm** $minus$ **1 from the dissociation limit of the b state), and one empirical scaling factor which takes account of neglected centrifugal constants higher than m//v. the overall standard error between computed and measured wavenumbers is equal to 0. 002 cm** $minus$ **1 in agreement with the differences of numerous independent absolute wavenumbers and the computed ones.
