Insight into vibration mode-resolved plasmon enhanced Raman optical activity

Vibration mode-resolved plasmon enhanced Raman optical activities (PE-ROA) are investigated experimentally and theoretically. It is found that the profile of PE-ROA is significantly different from that of ROA. Our experimental results revealed that PE-ROA is not a universal method for the enhancement of ROA. It should be very carefully for the using of plasmon enhancement for ROA.65
