Molecular Orbital Theory and Crystal Field Theory demonstrated the possibility of the complextion reaction between L-Cys and hemoglobin. 运用分子轨道杂化理论和配合物晶体场理论论证了半胱氨酸和血红蛋白之间发生配位反应的可能性。
Molecular orbitals describe the location of electrons in a molecular environment under the influence of more than one nucleus. 分子轨道可用来描述分子中在多个核作用之下电子定域情况。
