A diatomic molecule is made of two masses

{m_1}

and

{m_2}

which are separated by a distance

r.

If we calculate its rotational energy by applying Bohr's rule of angular momentum quantization, its energy will be given by: (

n

is an integer)

A
${{{{\left( {{m_1} + {m_2}} \right)}^2}{n^2}{h^2}} \over {2m_1^2m_2^2{r^2}}}$
B
${{{n^2}{h^2}} \over {2\left( {{m_1} + {m_2}} \right){r^2}}}$
C
${{2{n^2}{h^2}} \over {\left( {{m_1} + {m_2}} \right){r^2}}}$
D
${{\left( {{m_1} + {m_2}} \right){n^2}{h^2}} \over {2{m_1}{m_2}{r^2}}}$
