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

Vibrational motion involves the stretching and bending of chemical bonds, which requires more energy than rotational or translational motion. Therefore, it requires the greatest amount of energy to cause an excitation from the ground state to the first excited state.
