Abstract
The hyperfine structures of the EO + g (3 P 2) and of the (3 P 2) ion pair states of I2 were resolved in a two step excitation scheme using two single frequency lasers. For the E state the hyperfine coupling constants were derived for the v = 10, 11, and 16 vibrational levels. For the 1 g state, the v = 16 vibrational level was investigated. Molecular parameters of the nuclear electric quadrupole interaction, the magnetic dipole interaction and crossed second order contributions of the magnetic dipole and rotational interactions are deduced and interpreted within the separated atoms model.Keywords
