A molecular beam maser spectrometer was used to measure hyperfine structure on the J=1→ 0 rotational transitions in CH3CN and CD3CN. Measured nitrogen quadrupole coupling strengths are 1[formula omitted] for CD3CN. The deuterium quadrupole coupling strength along the C–D bond direction is [formula omitted] Nitrogen quadrupole coupling is discussed in relation to the electronic structure. Spin-rotation interaction strengths are reported. A convenient method for calculating matrix elements for hyperfine interactions in an arbitrary coupling scheme is presented.
