LIF spectroscopy of ScP

Electronic transitions of yttrium monophosphide

“…IrP [26] and ScP [21][22] were reported earlier. In this paper, we report the first experimental observation of the electronic spectrum of the YP molecule in the near infrared region between 714 and 885 nm using laser ablation/reaction free jet expansion and laser induced fluorescence …”

“…For ScP, our recent study observed the A 1 Σ + -X 1 Σ + transition [21], and found that the electronic structure and bond length (the excited A 1 Σ + state is shorter than the X 1 Σ + state) are similar to that for ScN. In the case of YN, fourteen electronic states as well as their corresponding spectroscopic constants were calculated at MS-CASPT2 level of theory (multistate complete active space second order perturbation theory) by Dou et al [24].…”

“…Several studies of ScN [18,19] and of ScP [19][20][21][22] have been attempted. The excited electronic states were extensively studied by Daoudi et al [19] using the multireference configuration CIPSI (configuration interaction by perturbation of multiconfiguration wavefunction selected iteratively) method as well as the DFT calculations at B-P86 level.…”
