Vibrational behaviour of the carbon–muonium bond in the muonated ethyl radical

Abstract

Using a variation-perturbation approach, harmonic and anharmonic corrections to some stationary point properties of the ethyl radical are computed for deuterium and muonium isotopomers. The anharmonic corrections in the muonated radical are found to be highly significant. The fundamental frequency for the C—Mu bond is calculated as 7877 cm^–1. The effect upon the muon–electron β-hyperfine coupling constant of excitation of the muonated radical to higher vibrational states is investigated.
