An Investigation of the Energy Levels of the Pt2+ Ion Using Multi-Reference Spin-Orbit Configuration Interaction Theory

This project sought to obtain more info for NIST's Atomic Spectra Database (ASD) by generating energies of the Pt²⁺ ion, whose current data is sparse. We used the COLUMBUS suite of codes to perform this task and calculated the energy levels and transition moments of Pt²⁺ under various symmetries using multi-reference spin-orbit configuration interaction calculations.
