簡化一個(gè)長句子
|
|
| 這個(gè)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.)比較長,請(qǐng)高手幫忙簡化成簡單明了的一兩句。 |

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. [ 發(fā)自小木蟲客戶端 ] |
