Determination of molecular constants of scandium triiodide monomer and dimer from electron diffraction data

The molecular intensity function of a ScI₃+SC₂I₆ mixture is solved using gas-phase electron diffractometry and taking into account the theoretical values of l(Sc-I). The symmetry of geometrical configuration, the internuclear distances, and vibration frequencies of the scandium triiodide monomer and dimer are determined.
