Just about to go into my PhD viva, my project included a whole year of obscure NMR techniques. Really glad to have a refresher on the basics though!

Thank you for the video. However, I do have a question. For the first example with the doublet, looking at the spectrum drawn it seems as though the chemical shift that is located downfield has a higher intensity than the one upfield. Shouldn't they be of equal intensity because they have equal probability of occurring? Or is that just convention?

incredibly helpful...one question though. Why cant a proton split another protons peak in the same environment (ie. one of the red protons split the others red peak)?
@vishnuvardhan337
@vishnuvardhan337 4 года назад
Because they are at same spectrum

I thought that atoms are more shielded appear down the spectrum and atoms shielded appear upfield

If we do the n + 1 rule, it would split into 2 peaks ? So why do the magnetic field thing
@alicia.katharina
@alicia.katharina 4 года назад
The magnetic field is the explanation for the rule. Sure you can just use the rule but if you have to understand why that rule exists, this is extremly helpful

awesome explanation, the right way of delivering science , you need to come over some shit universities and give a lectures to tell them to switch their way of learning

Hi, in the second example (6:40), aren't the two H on the top the equivalent protons? The H in the bottom has a different chemical environment. Thanks
@pratiksaha7699
@pratiksaha7699 Месяц назад
No, they are not because splitting is not observed due to coupling between protons making up the same - group, since they are equivalent. So, here in this example, the two protons at the top are not equivalent as they are attached to two different carbon atoms respectively. But, the two protons attached to the second carbon atom ( from left to right) are equivalent, as they are attached to the same carbon atom.

Organic Chemistry on Khan Academy: Carbon can form covalent bonds with itself and other elements to create a mind-boggling array of structures. In organic chemistry, we will learn about the reactions chemists use to synthesize crazy carbon based structures, as well as the analytical methods to characterize them. We will also think about how those reactions are occurring on a molecular level with reaction mechanisms. Simply put, organic chemistry is like building with molecular Legos. Let's make some beautiful organic molecules!
