How to Evaluate Rotational Constant using Rotational Energy?

Rotational Constant using Rotational Energy evaluator uses Rotational Constant given RE = Rotational Energy/(Rotational Level*(Rotational Level+1)) to evaluate the Rotational Constant given RE, The Rotational Constant using Rotational Energy formula is defined as related constant to energy of series of lines in rotational spectrum of a diatomic molecule. Diatomic molecules are often approximated as rigid rotors, meaning that the bond length is assumed to be fixed. Solving the Schrodinger equation for a rigid rotor gives the following energy levels: E=BJ(J+1). Rotational Constant given RE is denoted by B_RE symbol.
