摘要: The nuclear quadrupole hyperfine structure of H14N12C and D14N12C has been resolved in the laboratory for first time using millimeter-wave absorption spectroscopy. transient species were produced a pulsed DC discharge nozzle, Doppler broadening effects minimized by propagating millimeter waves coaxially with supersonic molecular beam. New rest frequencies J = 1-0, 2-1, 3-2 rotational transitions ground vibrational state determined. coupling constants derived from spectra are (eQq)N 264.5 ± 4.6 kHz 294.7 13.1 (eQq)D 261.9 14.5 D14N12C.
