【摘要】 根据原子结构的特点，探讨了双原子分子的键长与组成双原子分子的原子结构之间的关系，发现双原子分子的键长与组成双原子分子的原子结构之间存在着良好的定量关系，据此提出一种直接根据原子结构预测双原子分子键长的方法．结构表明，预测值与实验值的一致性令人满意，平均误差0．0058nm．更多还原

【Abstract】 Based on the characteristics of atomic structure,the relation between bond lengthof diatomic molecules and atomic structure was studied,and a new method was developedthat can be used to characterize the relationship between bond lenghth and atomic structure,and to predict the bond length of diatomic molecules. The calculated results showed that thepredicted values of bond length are in good agreement with the experimental data.更多还原
