How many rotational degrees of freedom does a rigid diatomic molecule have?How many rotational degrees of freedom does a rigid diatomic molecule have?

Options

  1. A0
  2. B1
  3. C2
  4. D3

Correct answer

C. 2

Step-by-step solution

How many rotational degrees of freedom does a rigid diatomic molecule have?
