The key feature of Bohr’s theory of spectrum of hydrogen atom is the quantization of angular momentum when an electron is revolving around a proton. We will extend this to a general rotational motion to find quantized rotational energy of a diatomic molecule assuming it to be rigid. The rule to be applied is Bohr’s quantization condition. In a CO molecule, the distance between C (mass = 12 amu) and O (mass = 16 amu), where 1 amu = 5/3 × 10^{-27}\,{kg}, is close to [JEE Adv 2010 P2]
