    Abstract

    The relationship between the muon electron hyperfine coupling constant and the C=O bond stretching frequency of a series of organic carbonyl compounds at 300K has been investigated. A linear relationship is shown to exist between these two properties, but for the aromatic carbonyl compounds only. This observation is shown to be in agreement with the presently accepted hyperconjugative mechanism of the hyperfine interaction in these systems. Muonium addition to the ring systems of these compounds was also observed and the hyperfine frequencies assigned and discussed.
