“…Recently, from the H + 2 HJE electronic energies, we determined the rovibrational energies and spectroscopic constants for 1sσ , 5f π, 6gπ , 6iπ, 6iφ, 7iσ [16] and 7jσ , 8jσ , 8kσ , 7iπ, 5gσ , 8jπ [17] electronic states. In this work, we extend these studies with the theoretical calculation of the H + 2 dynamical and spectroscopic properties using the HJE electronic energies for the 2pπ, 3dσ , 4dσ , 4f π, 4f σ , 5gσ , and 6iσ electronic states.…”
