【 摘 要 】

When observed spectrum of a diatomic molecule is expressed in terms of the Dunham coefficients 𝑌00, 𝑌10, 𝑌20, 𝑌01, and 𝑌11 only, dissociation energy of the molecule is given by 𝑌00 + 𝑌$^{2}_{10}$/(-4𝑌20). Kaur and Mahajan [1] have used the Dunham coefficients 𝑌10, 𝑌20, 𝑌01, and 𝑌11, for 15 vibrational states of 12 diatomic molecules (𝑌00 is zero for the cases accounted for), but their dissociation energy cannot be reproduced by the expression 𝑌$^{2}_{10}$/(-4𝑌20). Probable reason for the discrepancy has been discussed.
