Can someone help me identify these peaks for me? (Letters b and c)
« on: September 28, 2019, 01:54:02 PM »
 I don't know how to find the structures of the peaks because they are not given in my common fragments cheatsheet.
For the first graph's 52 peak, I am only given propyl (43) and butyl (57) in my list of common fragments.
For the second graph, between 55 and 72, I am given butyl (57) and pentyl (71).

If you assign a mass difference of 79-52 to some neutral molecule that can break away from pyridine, you will automatically get the formula of the 55 ion(printing error) 52 ion.

Think analogously for the second compound.

Does the 52 peak from pyridine have N in it? how can you tell?
