AbstractHigh resolution laser spectrum of scandium monoiodide (ScI) between 613 and 704 nm has been investigated using the technique of laser vaporization/reaction with free jet expansion and laser induced fluorescence spectroscopy. Seven vibrational bands of the D 1Π-X 1Σ + transition of ScI were recorded and analyzed. Accurate molecular constants for the v = 0-2 levels of the D 1Π state and the v = 0-3 levels of the X 1Σ + state were obtained. Detailed analysis of the recorded spectrum indicates that the v = 2 level of the X 1Σ + state is perturbed by the v = 1 level of the a 3Δ 1 state at J = 8. A comparison of molecular constants for the D 1Π and X 1Σ + states of scandium monohalides indicates a weakening of chemical bonding between the scandium and the halogen atoms down the group. © 2011 Elsevier Inc.
