#nmr spectroscopy

pov u made an entire inorganic chemistry themed Valentine’s Day poem including figures when u took it like 2 years ago

I find NMR spectroscopy really difficult, so I’m really excited that I passed that test. A lot of the difficulty stems from my general difficulty with Organic Chemistry due to a learning disability effecting my ability to visualize and logically reason 3-D objects in my head.

I didn’t pass it by much, but passing it means that I have a pretty good chance of passing this course just as long as I pass the Final Exam. :) I need just 50-53% on the Final Exam to pass this course.

I think I can pretty easily pass the final exam, because I didn’t do well on my first midterm exam because I was sick. And that material (Mass Spec & IR) is a lot easier than NMR. So as long as I can do well on that early material and do as well as I did on NMR, I should be ok.

Hey! IR and NMR takes a long time to get used to, very few people “get it” immediately. You’ll get so much better with practice, so I suggest a few things and a few different places to practice with! The first (to re-learn the basics) is Khan Academy. This website really helped me with a lot of concepts in undergrad! 

To practice NMR and IR, I suggest checking out the following:

Problem sets (they give you an nmr and you deduce the structure)

More problem sets with varying difficulty (also has COSY and DEPT spectra)

For predicting 1H or 13C NMR spectra, this is a website with SO MANY literature based values (used extremely frequently in grad. labs)

A spectral database for known, usually relatively uncomplicated compounds where you’re looking for their structure: 

My test is on mainly that (plus some IR Spec), and a lot of it is so complex that its hurting my head. I find IR spectroscopy & Mass Spectroscopy mostly straightforward.

But NMR, I don’t know. Its just tough for me. I understand the basics of it, but the more complex material is really hard for me to grasp (and that’s the stuff that’s likely going to be on the test).
