Question

for a rigid diatomic molecule ab ,the energy for rotational transition from j=o to j=1 state is 3.9cm inverse.calculate the energy for the transition from n=3 to 2​

Answer 1

Explanation:

Rotational energy levels of diatomic molecules are well described by the formula EJ=BJ(J+1), where J is the rotational quantum number of the molecule and B its rotational constant. B is related to the reduced. mass μ and the bond length R of the molecule through the equation B=h28π2μR2.
