[求助] 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.

最后的occur改为take place会更好,第一个indepebndent clause,楼主自己取舍,能力有限。

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.
