Abstract

Deuteron quadrupole coupling in DNCO was obtained from splittings of the 1₀₁ rotational state. The measured quadrupole coupling strength for the 1₀₁ rotational state is eqQ(1₀₁) = 53.6 ± 0.2 kHz, which leads to a value along the D-N bond eqQ_DN = 345 ± 2 kHz. Hyperfine splittings were observed using a molecular-beam maser spectrometer with 6-kHz resolution. The nitrogen quadrupole coupling strengths were eqQ(1₀₁) = 2123.0 ± 1.0 kHz for DNCO and eqQ(1₀₁) = 2052.7 ± 1.0 kHz for HNCO. High-precision values for the line-center frequencies and spin-rotation constants are also reported.
