Answer 2

The correct answer to this question is option (B) 0, 2B, 6B, 12B .....

Explanation:

• Diatomic molecules are frequently estimated as rigid rotors, indicating that the bond length is presumed to be fixed. Elucidating the Schrodinger equation for a rigid rotor gives the subsequent energy levels:

                                    $E(J) = B J(J+1)$

• In the given equation,  

• J = quantum number for total rotational angular momentum, and  

• B = rotational constant, which is associated with the moment of inertia

• Inertia, $I=$ μ$r^{2}$, where μ is the reduced mass and r is the bond length.

                                          $B=\frac{h}{8(pi)^{2}cl }$

• B is typically given in units of 1/cm, and the speed of light in this equation, c, has to be in cm/s rather than m/s. Using B in 1/cm will gives energy in the same units.
