A, B, C = rotational constants; b i, c i = b- and c-axis coordinates of the ith atom; e = charge on an electron; E = rotational energy; h = Planck's constant; I = moment of inertia, and the nuclear spin angular momentum quantum number; J = angular momentum quantum number; K = quantum number specifying component of J lying along the a-axis; m i = mass of the ith atom; q = electric field gradient; Q = … The rotational constant is dependent on the vibrational level: \[\tilde{B}_{v}=\tilde{B}-\tilde{\alpha}\left(v+\dfrac{1}{2}\right)\] Where $\tilde{\alpha}$ is the anharmonicity correction and $v$ is the vibrational level. As a consequence the spacing between rotational levels decreases at higher vibrational levels and unequal spacing between rotational levels in rotation-vibration spectra occurs.

rotational constant as $21.77\rm~cm^{-1}$. The rotational constant Bv for a given vibrational state can be described by the expression: Bv = Be + e(v + ½) where Be is the rotational constant corresponding to the equilibrium geometry of the molecule, e is a constant determined by the shape of the anharmonic potential, and v is the vibrational quantum number. Determining the rotational constant B . enables you to calculate the bond length R. The allowed transitions for the diatomic molecule are regularly spaced at interval 2B. The measurement and identification of one spectral line allows one to calculate the moment of inertia and then the bond length.
