← ScienceWhich outcome occurs when resonant infrared radiation impinges an organic molecule?
A)Increased molecular rotational excitation occurs✓
B)Accelerated nuclear fusion is initiated
C)Valence electron count becomes unstable
D)Intermolecular London dispersion forces weaken
💡 Explanation
Molecular vibrational modes selectively absorb infrared radiation due to quantized energy levels; energy transfer via **Absorption Spectroscopy** results in excitation, because molecules resonate at specific frequencies, therefore rotational and vibrational excitation happen, rather than electronic transitions or nuclear changes since they occur in other radiation conditions.
