Abstract

We have observed the rotational levels in the ν = 2, 3, 5, 6, 7, and 8 vibrational manifolds of the 2¹Δ_g state of ⁷Li₂ via the A¹Σ_u⁺ intermediate levels by δΛ = 2 transitions. This violation of the δΛ = 0, ±1 selection role is due to the interaction with the G¹Π_g state. Band-by-band deperturbations of the G¹Π_g to approximately 2¹Δ_g (ν_Π, ν_Δ) = (11, 2), (12, 3), (15, 5), (16, 6), (18, 7), and (19, 8) bands have been performed. Deperturbed molecular constants and rotational-electronic interaction parameters are reported here.
