Λ-Doubling investigation of the 51Πg Rydberg state of Na2 using optical–optical double resonance spectroscopy

Observation of the 7Πg State of Na2 by Optical−Optical Double Resonance Spectroscopy

“…The B v value decreases by about 0.008 33 cm -1 when v increases from 0 to 12, that is, B v decreases by 0.000 695 cm -1 per unit change of v . Dunham-fitted Y ij data (Table ) were used to construct the RKR potential of the 7 1 Π g (3s + 5p) state shown in Figure , together with potential curves of the 5 1 Π g (3s + 4d) state, , 6 1 Π g (3s + 4f) state, and the 2 ∑ g + ground state of Na 2 + , to have a pictorial view of the closeness among them. All the calculated potential curves are elevated by ∼230 cm -1 scaled with the experimental 5 1 Π g potential curve for close comparisons.…”

“…In particular, the Na 2 system has been studied for understanding different types of interactions playing important roles in diatomic molecules and to search for the answers to many intriguing questions about the fundamental physical properties of atoms and molecules. Researchers have carried out many works in investigating Na 2 using high level ab initio calculations , and experimental techniques − that involve many interesting and unusual features of the interactions.…”
