摘要：
We have observed with our intracavity CO2 laser Stark spectrometer the spectra of DCCCN with the CO2 laser lines 9P12 to 9P36. We have assigned 1565 Stark transitions which belong to 14 Δv5 = 2 transitions and essentially concern the three degenerate vibrational modes and their combinations up to about 2100 cm-1. A band by band analysis yields accurate values for the band centers, the electric dipole moments, and some rotational parameters. In spite of the anharmonic and vibrational l-type resonances, it was possible to determine some effective vibrational parameters, including r56. As an auxiliary result we have succeeded in observing the hyperfine structure due to 14N in a P(1) transition between Σ states. © 1990.
