Radial Functions of CH⁺ in the Electronic State a ¹Π

Abstract

From published data of the spectral parameters of ¹²C¹H⁺ and ¹²C²H⁺ in the A ¹Π electronic state, the dependences on internuclear separation R of the internuclear potential energy, the adiabatic and non-adiabatic contributions to the molecular energy, and the interaction of the electronic orbital and rotational angular momenta have been derived, all applicable within the range 0.99 < R/10^-10 m < 1.90.
