Research output: Contribution to journalArticlepeer-review

12 Scopus citations


Hyperfine structure on the J = 1→0 transition in CH3NC was observed using a molecular beam maser spectrometer with 6 kHz resolution. Molecular parameters obtained from an analysis of the spectrum are: the nitrogen quadrupole coupling strength eqQ = (488.5±1.0) kHz, the nitrogen spin-rotation strength CN = (1.45±0.5) kHz, the hydrogen-hydrogen spin-spin interaction strength DHH = (21.33±0.5) kHz and the hydrogen spin-rotation strength CH = (-0.3±0.5) kHz.
