摘要 在 26.5–40.0 GHz 频率范围内观察并分配了二氟丙二烯酮的正常和两种单取代同位素异构体的微波光谱。对于正常物种,旋转常数确定为 A = 11 558.126±0.004,B =2023.911±0.001 和 C =1720.649±0.001 MHz。对于羰基 13 C 和 18 O 物种获得了相当精确的结果。斯塔克效应测量导致总电偶极矩为 μ T =0.671±0.012 D,成分为 μ a =0.418±0.013 D 和 μ b =0.525±0.003 D。与母体丙二烯酮分子相比,二氟物质没有显示大振幅隧道运动的证据。然而,数据清楚地表明,该分子从 C 2v 对称性强烈扭曲,其具有与丙二烯酮类似的弯曲的枯草酮链。

effect measurements led to a total electric dipolemoment of μ T =0.671±0.012 D with components of μ a =0.418±0.013 D and μ b =0.525±0.003 D. In contrast with the parent propadienone molecule, the difluoro species shows no evidence of large amplitude tunneling motions. However, the data show clearly that the molecule is strongly distorted from C 2v symmetry with a cumulenone chain that is bent similarly
