Potential energy curves, transition and permanent dipole moments of KRb

Investigation on the fine structure of the B 1∏ − c 3∑+ complex in KRb

“…For the current analysis this subspace consists of two sets of rotational terms. One is for the B 1 Π electronic state with vibrational quantum number v ′ = 2 and the other for the c 3 Σ + electronic state with v 0 (≈ 35, estimated from the theoretical potentials [5,6,8], although the exact value is not required for the model). This subspace is even further restricted for rotational values J ′ ∈ [22, 61] such that the region of perturbation is included and isolated from other perturbation centers.…”
