简化一个长句子
|
||
| 这个句子（The decrease of the C=C stretching vibration frequency for polyene of increased the conjugation length has been explained by assuming that, with the increase of the conjugation length, the π-electrons delocalization tends to equalize the CC bond lengths, thereby decreasing the bond order of C=C bonds and causing a lower C=C stretching frequency for longer polyene.）比较长，请高手帮忙简化成简单明了的一两句。 |

Associating with the increase of the conjugation length, the π-electrons delocalization tends to equalize the CC bond lengths. In this case, the bond order of C=C bonds might decrease,and hence a lower C=C stretching frequency for longer conjugation length of polyene would occur. [ 发自小木虫客户端 ] |

| The C=C stretching vibration frequency is decreased by the increased conjugation length of polyene, because with the increase of the conjugation length, the π-electrons delocalization tends to equalize the CC bond lengths, for instance decreasing the bond order of C=C bonds, thus resulting in a lowered lower C=C stretching frequency for longer polyene. |
