Finding the molecular formula from a mass spectrum

This is the first in a series of 3 lessons about the interpretation of electron impact mass spectra. This video was created for a university course in instrumental analysis in chemistry.

They need to invent a better machine, this is ridiculous.

Gary you are a gem! My professor is fanastic in her field but I'm afraid teaching isnt quite for her, and this really helped me out!! Thank you!

THIS IS THE BEST AND MOST COMPREHENSIVE VIDEO ON MASS SPEC THANK YOU!

[borghiire]

Thank You so much Doctor Mabbott! These videos are very helpful and so well spoken. I'm using them to better understand these concept as my Analytical Chemestry exam is in 4 days and I want a good grade!
Immense gratitude from the University of Pisa, Italy!

I almost feel bad for the fact I'm paying my lecturer who couldn't (and also wouldn't) explain this in weeks when you managed to explain it in minutes.

Thank you for the video! It was a life saver

Seriously why can’t all my professors explain like this, you just saved my life by explaining it in a way I can understand, smh this is not that complicated as my professor make it out to be. Thank you 🙏🏾

[theoverlord]

Best lecture ive seen yet on this subject thanks man

[Errys]

you explained it better than my university professor, thank you

[thomasn]

dis vid is hella helpful bruh, the way u explain it is hella lit. u make somethin hella confusin easy to understand. u da real mvp swag yolo swag swag. deuces, ratchet tom!

[wilwilliams]

Very helpful and well explained! I've been looking for a good video to explain how to interpret M.S spectra.

[toulinma]

Wow. You managed to explain how to interpret a mass spectra without saying what fragmentation is. That's not that easy. Good job 👌🏻

[hollietaylor]

Thanks, Gary! You just answered my prayers!!

[bfybfy]

You saved me. I wish I found your video a long time ago. Thank you.

[fatmaelsayed]

thanks a million. today you kindly enlightened me with those precious tips about how molecular formulae are guessed based on the vaue of m/z ratio

[lorebroker]

This is an insanely well explained lecture. Thanks a lot!

[hadassachata]

Please come back sir, the world need you

[Yo-fmwk]

Please explain the formula @11:50. I understand the 4.2/100 is the intensity of M+1 / M intensities, but why are they multiplied by 100/1.1?

[Shantanu-bhcj]

From where are you calculating the intensities of atom.. like at 13:39. Can you please explain it once.

[MrKippie]

Thank you!
By the way, just a tip: If you give a link in one of your next videos; put the link in the description!

Thank you for explaining this so thoroughly it helped me so much!!!
