• # Abstract

When observed spectrum of a diatomic molecule is expressed in terms of the Dunham coefﬁcients $Y_{00}$, $Y_{10}$, $Y_{20}$, $Y_{01}$, and $Y_{11}$ only, dissociation energy of the molecule is given by $Y_{00} + Y^{2}_{10}/(-4Y_{20})$. Kaur and Mahajan [1] have used the Dunham coefﬁcients $Y_{10}$, $Y_{20}$, $Y_{01}$, and $Y_{11}$, for 15 vibrational states of 12 diatomic molecules ($Y_{00}$ is zero for the cases accounted for), but their dissociation energy cannot be reproduced by the expression $Y^{2}_{10}/(-4Y_{20})$. Probable reason for the discrepancy has been discussed.
