Abstract

The electronic transition spectrum of scandium monophosphide (ScP) molecule in the visible region between 480 nm and 550 nm has been recorded and analyzed using laser ablation/reaction free-jet expansion and laser induced fluorescence spectroscopy. The ScP molecule was produced by reacting laser - ablated scandium atoms with PH$_{3}$ seeded in argon. Ten vibrational bands were recorded and they are identified to be belonging to three electronic transition systems, namely the [19.1]$^{1} \Pi_1$ - X$^{1} \Sigma$ transition, [19.5]$^{1} \Sigma$ - X$^{1} \Sigma$ transition, and [19.8] $^{3} \Pi_i$ - X$^{3} \Pi_i$ transition. ScP has been determined to have a X$^{1} \Sigma$ ground state in our earlier work. A least squares fit of the measured rotational lines yielded molecular constants for the single and the triplet electronic states. Theoretical calculation results have been used to help the assignment of the observed electronic states.
