Using Bohr's quantization condition, what is the rotational energy in the second orbit for a diatomic molecule. (I = moment of inertia of diatomic molecule, h = Planck's constant)

Options

  1. An² 2 ~T ²
  2. Bh 2 I ²
  3. Ch 2 I ²
  4. Dn² 2 I² ²

Correct answer

A. n² 2 ~T ²

Step-by-step solution

According to Bohr's quantization condition L = nh 2 = 2 ~h 2 = h [ . For 2^ nd orbit ] Rotational KE = 1 2 L ² I = 1 2 h ² I ²
