Bound to free transitions of ScI were observed for the first time after photoexcitation of ScI3 in the ultraviolet by 193~nm radiation from an ArF excimer laser. Broad fluorescence features typical of molecular transitions between different vibrational energy levels of Sc*+I have been measured in the near-infrared between 860 and 940~nm.
Many narrow spectral lines have also been observed, but were attributed to fluorescence of atomic Scandium or Iodine.
Experimental and simulation results will be compared and presented.
