Spin Spin Splitting - N+1 Rule - Multiplicity - Proton NMR Spectroscopy

This organic chemistry video tutorial provides a basic introduction into spin spin splitting / coupling as it relates to proton NMR spectroscopy. It explains how to use the N+1 rule to determine the multiplicity of a H NMR signal. It also discusses the intensity ratio of singlets, doublets, triplets, quartets, quintets, sextets, and septets using pascal's triangle. It also provides an intro into complex splitting by using a triplet of quartets and a quartet of triplets signal as an example which can be simply referred to as a multiplet.

[@Casualbystander]

My advice would be to focus solely on your work now. As fascinating as this is, you’ll eventually learn it one day. I used to look into material way beyond what I was learning while in high school too, and although it was fascinating I created a delusion in my head that somehow I was benefiting from spending so much time looking into material for the future. You’ll come across this one day. I’m only watching it because I have to-I’m taking organic chemistry in college.

Thanx for explanation. Correction : 1.6 is actually upfield to the chemical shift, going to the 0. Downfield = Deshielfed. (Both have "D" in the beginning.

[@gardeningnm]

Looking at the middle peak of the triplet what would cause one proton to be aligned with the magnetic field and one against? Is it to do with shielding and de shielding?

[@mdabdullahalnahid5886]

great lesson. thanks

[@rahafrahaf73886]

Thank you! But can someone explain how is it at the highest frequency when it's furthest down and high B°? Then alligned with the magnatic field

[@uuuuu1781]

If you have a high magnetic field (B) influencing the nucleus you have a peak at a high frequency in a NMR spectrum, and high frequency peaks are called downfield and low frequency peaks are called upfield as far as I understood.
