摘要: The rotational spectrum of the slightly asymmetric top, vinyl cyanide, has been investigated in a microwave spectrograph employing Stark effect modulation and direct absorption cell. constants = 49 076.2 Mc/sec, b 4971.33, c 4514.05 were computed from observed frequencies J 2→3 transitions. From measurements effect, components dipole moment found to be μa 3.68D, μb 1.25, μ 3.89. Partial resolution hyperfine structure certain lines gave value —3.0 Mc/sec for ξaa component quadrupole coupling.
