【Abstract】 The study on the Cydta have been performed,with ab initio calculation by means of Hatree-Fock/6-31G basis set in Gaussian 03 package,where Cydta= cyclohexane diamine-tetracetic acid.The geometry structure of the Cydta have been optimised.The stabilities of the compound, the energies of frontier molecular orbital,the composition of frontier molecular orbital,the populations of the atomic net charges have been investigated.Some results obtainted may be useful as references for synthese and sdudy of the Cydta complex.Electrolic mulliken of the atomic changes have been investigated.We have been tried to find their regularity,supplying the meaningful director for the experimental investigation.更多还原
