请各位大侠翻译: 这是一篇1,5萘二胺氧化聚合英文论文的一段节选,很不理解: As follows from the IR spectra of poly-substituted naphthalenes, absente of the band of medium intensity between 860 and 900 cm-1 excludes substitution with isolated CH groups. This is the case with our polymer. Thus, all possible structures that contain units with one isolated aromatic H atom in the naphthalene ring may be excluded. The very strong band with two components at 764 and 770 cm-1 observed in the spectrum of the monomer can undoubtedly be assigned to CH out-of-plane bending vibrations of three adjacent CH groups. 尤其不懂 isolated CH groups的意思.

As follows from the IR spectra of poly-substituted naphthalenes, absente of the band of medium intensity between 860 and 900 cm-1 excludes substitution with isolated CH groups. This is the case with our polymer. Thus, all possible structures that contain units with one isolated aromatic H atom in the naphthalene ring may be excluded. The very strong band with two components at 764 and 770 cm-1 observed in the spectrum of the monomer can undoubtedly be assigned to CH out-of-plane bending vibrations of three adjacent CH groups. 由下面的多聚取代萘的红外光谱，860和900 cm - 1之间的中等强度光谱带的缺乏，排除了中间CH官能团取代这一可能。我们的聚合物正是这种情况。因此，所有可能包含带一个孤立芳香氢原子的萘环的单元的结构都可以被排除在外。在单体的光谱中包含764和770 cm - 1两个峰的非常强的谱带毫无疑问可以认定是3个相邻的CH官能团的键合振动平面之外的CH官能团的光谱。 注：bending 的翻译可能有点不太确切。不好意思，想不起来了。 [ Last edited by DifficultFlying on 2009-1-30 at 22:38 ] |
