Introduction to IR Spectroscopy: How to Read an Infrared Spectroscopy Graph

Рет қаралды 396,065

4 жыл бұрын

In this video I will give you an introduction to infrared spectroscopy and explain what the graphs mean and how to interpret a spectroscopy graph. This is pitched at the level of A level and AS chemistry but can be used beyond that. I will show you how to interpret the peaks on the graph to work out what functional groups are present in a substance and explain the significance of the fingerprint region of an IR spectrum.

how do you interpetate the transmittance? like, if I make a IR graph with a molecule, how do I know how much transmittance every peak is?

Thanks for your detailed explanation. Yet, may I know why we cannot use the fingerprint region to identify a compound if it is unique? Why are we required to identify all the functonal groups of a respective molecule so as to distinguish the compound in exams instead? thanks a lot

@AA-gl1dr 3 жыл бұрын

So that you are able to interpret the data at a glance. It’s useful in reaction monitoring, quality control, forensics, etc. The fingerprint region is not easily memorized.
