Question

Select One Option Correct from the following : The key features 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. It is found that the excitation frequency from ground to the first ex- cited state of rotation for the CO molecule is close to $\frac{4}{\pi} \times 10^{11}$ Hz. Then the moment of inertia of CO molecule about its centre of mass is close to $[take h= 2\pi\times10^{34} Js]$
(A) $2.76\times10^{46} kg m^{2}$
(B) $1.87\times10^{-46} kg m^{2}$
(C) $4.67\times10^{-47} kg m^{2}$
(D) $1.17 \times 10^{-47} kg m^{2}$
