is shown to exist between fluxional behaviour in the σ-cyclopentadienes 5-RC5H5(R = H, CH3, SiH3, GeH3, or SiF3) and the relative positions of the two photoelectron bands due to the ring π-bonding electrons. For R = PF2 and SiCl3 interactions between the second ring level and non-bonding orbitals of R have to be taken into account. It is suggested that the fluxional behaviour arises from interaction
显示出在σ-环戊二烯5-RC 5 H 5(R = H,CH 3,SiH 3,GeH 3或SiF 3)中的通量行为与两个光电子能带的相对位置之间存在密切相关性。环π键电子。对于R = PF 2和SiCl 3,必须考虑第二个环能级与R的非键轨道之间的相互作用。有人建议,该fluxional行为从R-C的相互作用产生5与对称环π键的水平,这是那些表现出快速fluxional行为化合物中最大的σ键合的水平。
