Links to articles or advice from personal experience appreciated.
Discussions about GC-MS, LC-MS, LC-FTIR, and other "coupled" analytical techniques.
Yes, it happens by redox mechanism of ESI (formation of radical molecular ion). I've had experience with that with carotenoids, PAHs and other redox sensitive molecules.mrmiller wrote:
I've found a few unknown identification papers and the occasional mechanism contains a radical.

Yes, its called "even-electron rule", but... Although it's not common for formation of ion-radical fragments (odd-electron ions) from pseudo-molecular ions (even-electron ions) at CID, but it happens.mrmiller wrote:
Some people I've discussed fragmentation with say you shouldn't see radical formation at all in ESI MS/MS.
