双原子氢化物键长的一种经验计算李晓梅（重庆师范学院化学系，重庆，６３００４７）用经验公式计算分子键长，往往与实验值偏差较大￣［１－３］。徐宝庆￣［４］的方法较准确，但由于公式涉及的参数较多而给计算带来困难。已响。的文献虽然作了一些改进￣［５，６］，但... An empirical calculation of the bond length of diatomic hydride Li Xiaomei (Department of Chemistry, Chongqing Normal University, Chongqing, 630047) The empirical formula for calculating the bond length often has a large deviation from the experimental value [1-3]. Xu Baoqing ~ [4] method is more accurate, but because of the parameters involved in the formula more difficult to calculate. Already ring Although made some improvements in the literature [5,6], but ...
