基于MO理论,提出了双原子分子结构稳定性分析模型。利用突变论方法在不具体求解薛定谔方程的情况下,对其久期行列式所表示的势进行分子的结构稳定性态分析,论证了分子存在的内在本质,并给出了分子平衡态势表达式,获得了与量子化学一致的结论。若给键参数(?)赋予更多的化学信息,结果会更合理。 Based on the MO theory, a biomolecule structural stability analysis model is proposed. By using the method of catastrophe theory, without analyzing the Schrödinger equation, the structural stability of the molecule represented by the determinants of its duration is analyzed. The intrinsic essence of the existence of the molecule is demonstrated and the expression of the molecular equilibrium , Obtained consistent with the conclusion of quantum chemistry. If you give the key parameters (?) More chemical information, the result will be more reasonable.
