| 另一方面，我们从图一可以看出随着浓度逐渐降低，~1000cm-1处的CH3拉曼峰消失。众所周知，β-胡萝卜素的CH3与CC单双键都为共振拉曼效应增强，而随着浓度降低CH3键的拉曼峰消失，说明CC单双键与CH3在这种情况下增强机制不同。 |

| On the other hand, the peak at 1000cm-1 disappeared in Raman bonds with concentration decreasing (see figure 1). It is known that the methyl and double bond of β-carotene enhanced by resonance effect of Raman. The disappearance showed the enhanced mechanism of the methyl and double bond was different. |

As we know, CH3 of β-carotene and CC double bond were enhanced as single-resonance Raman Effect. As concentration of CH3 reduced, the peak disappeared, indicating CC single and double bond and CH3 in this case show different enhancing mechanism. |

| On the other hand, Figure 1 showed that the Raman peak of CH3 degraded with the decrease of the concentration and disappeared at ~ 1000cm-1. It was well known that the Raman Effect enhanced when CH3 in β-carotene and the single-double bonds of CC were both resonance. And the result indicated that the enhancing mechanism of CH3 in this case made a great deal of difference to that of the single-double bonds of CC. |
