Fragmentation in mass spectrometry 

Greg Doucette: put all points into Strength Alan Doucette: put all points into Intelligence

Smarter than last time I'm here after i got my daily dose of yelling from Dr. Greg

Thanks a million for all your great videos on MS Spect., you did a great job in presenting a high tech and complicated topic in a simple and understsndable way. I really enjoed watching them.

I do not usually comment but wow thanks for going into this....I still will need to study it more but nice to see it explained as not such a clear cut process. Thanksss

Your videos are great! Thanks a lot for all of your effort:)

Hello, could someone explain how you find an hexane from counting 3 CH2 and 1 CH3 at 11:37 please ? Where do you see the other 2 CH2 ?

Sick explanation bro

Any differences between the d and l form of glutamine are not due to differerences between the d and l form of gritainnes in the MS. These enantiomers fragment in exactly the same way.

Thanks for the video!

McLafferty rearrange is the retroene reaction. Look at the mechanism and sort out for yourself why this should be the low-energy sigmatropic process.

Pushing the arrows LoL Talk about stabilities of charged species instead of how they come about.
