Abstract

We present a high-resolution analysis of the six electronic states that share the same dissociation limit with the second excited electronic state B in molecular iodine. These six states are coupled to the B state via hyperfine interactions. The four hyperfine parameters, C B , δ B , d B , and eq Q B , are calculated with the available potential energy curves and wave functions constructed from the separated-atom basis set. We obtain a maximum separation of the respective contributions from all six electronic states and compare each individual contribution with high-precision spectroscopic data, providing an independent verification of the relevant electronic structure.
