A parameter-free analytical formula for dissociation energies of diatomic molecules is proposed by Fan and Sun (2009) [20] based on LeRoy and Bernstein's vibrational energy expression near dissociation limit. Using three highest vibrational energies which may be generated by the algebraic method (AM) presented in our previous study and by some other physical methods, the new formula is applied to study the molecular dissociation energies of 10 electronic states of KH, (7)LiD, (7)LiH, (6)LiH, NaK, NaLI and NaRb heteronuclear diatomic molecules which have regular (Morse-like) potentials in this work. The results show that the AM energies E(upsilon)(AM) and dissociation energies D(e)(AM) have excellent agreement with experimental values.
范和孙（2009）[20]基于 LeRoy 和 Bernstein 在离解极限附近的振动能表达式，提出了一种用于双原子分子离解能的无参数解析公式。利用我们之前研究中提出的代数方法（AM）和其他一些物理方法可能产生的三个最高振动能，该新公式被应用于研究 KH、（7）LiD、（7）LiH、（6）LiH、NaK、NaLI 和 NaRb 异核双原子分子的 10 个电子态的分子离解能，这些分子在这项工作中具有规则（类 Morse）势能。结果表明，AM 能量 E(upsilon)(AM)和离解能 D(e)(AM)与实验值具有极好的一致性。
