The adiabatic channel interaction potentials for a system charge + dipole-open-shell-quadrupole linear rotor are calculated in the perturbed rotor and slightly anharmonic Renner-Teller limits. In both cases, first order charge-dipole and charge-quadrupole interactions are not additive; this leads to novel expressions for the energy levels. The result can be used in the construction of the adiabatic correlation diagrams between free rotor states with account for the Λ-doubling of a diatom and the linear anharmonic Renner-Teller triatomic system.
