ether) pentadienyllithium has been calculated by the CNDO/2 method. The metal—anion interaction involves both σ and π bonding. The effect of methyl Substitution on the electronic structure of the solvated species has been evaluated. In general, the electronic effect of a methyl group is substantially less for the solvated structure than for the isolated anion.

锂的部分几何优化结构已通过CNDO / 2方法进行了计算。
金属-阴离子相互作用涉及σ键和π键。已经评估了甲基取代对溶剂化物质电子结构的影响。通常,对于溶剂化的结构,甲基的电子效应明显小于对分离的阴离子的甲基的电子效应。
