Interactions of the 3pπᵤc¹Πᵤ(v=2) Rydberg-complex member in isotopic N₂

Vieitez, M. O.; Ivanov, T. I.; de Lange, C. A.; Ubachs, W.; Heays, Alan; Lewis, B. R.; Stark, G.


The 3pπᵤc¹Πᵤ−X¹Σg⁺(2,0)Rydberg and b′¹Σᵤ⁺−X¹Σg⁺(7,0) valence transitions of ¹⁴N₂, ¹⁴N¹⁵N, and ¹⁵N₂ are studied using laser-based 1 extreme ultraviolet (XUV)+1′UV two-photon-ionization spectroscopy, supplemented by synchrotron-based photoabsorption measurements in the case of ¹⁴N₂. For each isotopomer, effective rotational interactions between the c(v=2) and b′(v=7) levels are found to cause strong Λ-doubling in c(v=2) and dramatic P∕R-branch intensity anomalies in the b′−X(7,0) band due to the...[Show more]
