The spacing of lines in the microwave spectrum of 35Cl19F is 1.033 cm-1, what is the value of the rotational constant? In rotational spectroscopy of diatomic molecules (modeled as a rigid rotor), the wave numbers of the spectral lines are given by the formula: wavenumber = 2B(J+1), where J is the rotational quantum number of the lower state and B is the rotational constant.
