Spectroscopy

Read our general notes on Risk Assessment

The developments in spectroscopy have transformed the subject by allowing chemists to study the behaviour of particular atoms, molecules or chemical bonds.
 
In most advanced chemistry course you are expected to be familiar with:

mass spectrometry

visible of ultra-violet spectroscopy

infra-red spectroscopy

nuclear magnetic resonance spectroscopy (nmr).

In most AS courses you really only have to know about mass spectrometry and possibly the basic concepts of infra-red spectroscopy. The other instrumental methods are part of the for A2 programme.

Recently Asked Questions

• How do we find the value of the peaks in mass spectrum questions? I would like to know how to attempt this type of question in general. 120409
• The error of a colorimeter is 2%, so what do I do with this value? I know I have to do something with the calibration curve, but where am I reading from, it's obviously from the absorbance axis, but what value? Then do I have to find the error for every step in one experiment, i.e every 10 seconds, because I'm sure the error would go over 100%? Thanks in advance. 180309
• How do you distinguish aldehydes from ketones by comparing their infrared spectra? 260109
