Which is an example of an attment in pyridine?
An example in attment is the spectrum of pyridine, and its mixture with THF containing however significant amouunt of H2O. If you have not this indication the origin of band at 3400 cm-1 would be of other inpurities. Can you help by adding an answer?
What do you need to know about the IR spectrum?
The IR Spectrum Table is a chart for use during infrared spectroscopy. The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. There are two tables grouped by frequency range and compound class. Use this table when you already know the frequency of your material.
What does 3400 cm-1 mean in pyridine?
It seems that this peak relates to H2O. A peak at 3400 cm-1 in pyridine IR spectrum is unusual. It cannot be attributed to N-H since pyridine does not have N-H. If the peak is broad, then I agree with Dr. Ravi shekar that it indicates the presence of water but in (good) amount.
How is pyridine used to analyse acidic catalysts?
