【求助】红外谱图(图传好了)
图中一个是铅离子和3,4-二羟基苯甲酸的混合物红外谱图,另一个两者是经过化学反应后的红外谱图。样品是干燥粉末,KBr压片。
我想知道的是反应后芳环还存在么,量大不大?反应后主要是哪类物质?烯烃?邻二酮?
烦请解答,谢谢!
如能给予详细解释,金币可以增加!

你的图看不到
想邦你也没办法
从图上看,你的纵坐标应该是T值。
一般情况下,苯环的吸收峰在1600 nm左右,对比原产物,
苯环的吸收峰应该是已经破坏了,苯甲酸类的物质,经过反应产生新的基团,
一般情况下都是苯环上的C-C键被打开。
至于反应产物你可以找一个相关的红外分析材料对比一下峰值。
从你这个图上不容易看出新峰的具体位置。
这是数据,看能否进一步帮忙分析一下,金币好说。

你给的数据不是很完整,波段主要是400-1797,
对比反应后的红外曲线,主要在2250左右产生了两个新的峰,
你这个图是用origin做的,你可以红外工作站打开你的图谱,
点这两个新峰,确定其横坐标,对应这两个横坐标去百度里搜索红外吸收峰。
确定其基团。
呵呵,原始数据也贴来了
http://www.science-and-fun.de/tools/
把这个网站发给你,希望对你的图谱分析能够有所帮助,
这个这个网站你只要把新峰的横坐标输入进去,就可以出现可能的基团,
不过具体的还要参考别人的文献来确定。
