用气体电子衍射法测定了VCl4和TiCl4的分子结构。与TiCl4相比，VCl4中Cl-Cl距离的均方振幅异常大。这归因于VCl4中的振动相互作用。观测到的均方振幅导致了一阶振动相互作用常数|a ' |的评估。其他实验结果，如键长，收缩效应，和振动谱讨论了有关理论的振动相互作用。
The molecular structures of VCl4 and TiCl4 have been determined by gas electron diffraction. The mean square amplitude of the Cl–Cl distance in VCl4 is found to be abnormally large compared with that of TiCl4. This is attributed to the vibronic interactions in VCl4. The observed mean square amplitude has led to the evaluation of the first‐order vibronic interaction constant |a′|. Other experimental results, such as bond lengths, the shrinkage effect, and vibrational spectra are discussed in relation to the theory of vibronic interactions.
