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 \over 3} \times {10^{ - 27}}

kg, is close to :

A
2.4 $\times$ 10 $-$ 10 m
B
1.9 $\times$ 10 $-$ 10 m
C
1.3 $\times$ 10 $-$ 10 m
D
4.4 $\times$ 10 $-$ 11 m
