Abstract

High resolution measurements of hyperfine structure on the J=1→0 rotational transitions in ¹⁴N₂O were made with a molecular beam maser spectrometer. All seven hyperfine components arising from quadrupole interactions by two nitrogen nuclei were completely resolved. This permitted determination of both quadrupole coupling constants as well as the two spin-rotation constants. Values of the best least-squares fit parameters are (eqQ)_end=-776.7±1.0 kHz, (eqQ)central=-269.4±1.8 kHz, M_end=-2.35±0.20 kHz, and M_central=-2.90±0.26 kHz. The spin-rotation constants are used to calculate magnetic shielding parameters for the two nitrogen nuclear sites. The 1→0 rotational transition frequency is 25 123 246 kHz.
