关于诱导效应对YnX-H型分子氢化物中UX-H的影响,文献上曾以电负性、Taft常数等来进行定性或定量描述,虽然取得一些结果,但对其普遍规律性尚缺乏深入系统地探讨。在文献中作者曾建议用原子的价电子数n与共价半径γ的比值作为量度原子电负 The effect of induction on UX-H in hydride of YnX-H type has been described qualitatively or quantitatively by electronegativity and Taft constant in the literature. Although some results are obtained, its general regularity is still lacking Systematically explore. In the literature, the authors suggested that the ratio of the valence number n of atoms to the covalent radius γ should be used as a measure of the atomic electronegativity
