Question

Quizplus · Accepted Answer

Molecular lines are more complex than elemental spectral lines because molecules can vibrate and rotate in addition to electronic transitions, resulting in a broader range of energy levels and corresponding spectral lines. Molecules can vibrate and rotate, providing additional energy states and transitions that result in more complex spectral lines compared to elemental spectral lines.
