采用我们曾根据量子力学推导出的k公式建立了Cu的双态杂化表,分析了Cu的价电子结构。以键距差|ΔD|≤0.005nm为判据,讨论了Cu的可能杂化状态。结果表明所给出的新k公式确定的杂化台阶的个数比用EET给出的k公式确定的杂化台阶的个数少,初步解决了固体中原子杂化态的不确定性问题。 Based on the k formula derived from quantum mechanics, we have established the dual-state hybrid table of Cu and analyzed the valence electron structure of Cu. Taking the bond distance difference | ΔD | ≤0.005 nm as criterion, the possible hybridization state of Cu was discussed. The results show that the number of hybrid steps determined by the new k formula is smaller than the number of hybrid steps determined by the k equation given by EET, which initially resolves the problem of the uncertainty of hybrid states of atoms in solids.
