Question

ir absorption is accompanied by the transition​

Answer 1

Answer:

Absorption Spectroscopy The first route occurs when absorption of radiation leads to a higher rotational energy level in a rotational transition. The second route is a vibrational transition which occurs on absorption of quantized energy. This leads to an increased vibrational energy level.

Answer 2

Answer:

Yes,absorption is accompanied by the transition

Explanation:

Because when there is absorption of energy,the electrons get excited and transition occurs
