How do you obtain Anharmonic potential constant?

When changing the energy of the vibrational levels, anharmonicity has another, less obvious effect: for a molecule with an Anharmonic potential, the rotational constant changes slightly with vibrational state. The rotational constant for a given vibrational state can be described by the obtained expression, where Be is the rotational constant corresponding to the equilibrium geometry of the molecule, αe is a constant determined by the shape of the Anharmonic potential, and v is the vibrational quantum number. Anharmonic potential constant is obtained when we reframe the expression to obtain the desired output.
