Of the three modes of molecular motion-vibration, rotation, and translation-which requires the greatest amount of energy to cause an excitation from the ground state to the first excited state?

Question

Quizplus · Accepted Answer

Vibration requires the greatest amount of energy for excitation from the ground state to the first excited state because it involves changing the bond lengths and angles within molecules, which is more energy-intensive than rotation or translation.
