A novel technique has been described in the present studies for the measurement of emission cross sections of excited state species formed in ion–molecule reactions and has been applied to the case of collisions of N+/Ar+ ions with HgI2 molecules. Emission spectra of HgI radical due to (BX) transition from highly excited levels to lower levels have been observed and identified. Using the integrated intensity of the most intense band of the HgI (B2Σ+, v′=0−X2Σ+, v″=22) transition at 445 nm, emission cross sections were measured in the kinetic energy range of 100–1000 eV (laboratory frame).
