摘要: The structures of methoxide ion, ethoxide tert-butoxide fluoromethoxide and trifluoromethoxide ion were obtained via geometry optimizations with the 6-31G* 6-311++G** basis sets. In all cases, carbon-oxygen bond shortened about 0.1 A on going from alcohol to alkoxide whereas bonds attached carbon increased in length. origin changes lengths was studied use Bader's theory atoms molecules
