I apologize for disregarding the template, but it did not seem necessary or practical for my question. In molecules which has more energy, a rotational or vibrational state (first state for both)? I've just calculated the vibrational and rotational energy of an HCl molecule and my results show that the vibrational energy is dramatically less then the rotational energy. From previous knowledge I thought the vibrational energy would be more. Thank you for your time.
