Abstract. Statement
of Kaur and Mahajan [1]
about the definition of
$\Delta$ used by Chandra [2] is not correct. Even if we take
$\Delta = \mu \omega_e^2 r_e^2/2 D_e$, the relation between
$\Delta$ and $G$(=$8 \omega_e x_e/B_e)$ is obtained as $\Delta =
4.21452856 G$, provided the vibrational
energy of a diatomic
molecule is expressed in terms of
limited Dunham coefficients,
$Y_{10}$, $Y_{20}$, $Y_{01}$ and $Y_{11}$. This relation is still
different from that of Kaur and Mahajan [3].
Keywords. Diatomic molecules; dissociation
energy; equilibrium distance.
