Best way to learn NMR/IR?

[jammin06]

Anyone have any links to sites that teach NMR/IR in a clear and concise manner? Situation has it that I will have completed a year of orgo by this summer without having covered NMR or IR.
(took orgo I over the summer at state school, taking orgo II in the spring. different cirriculums at each location. NMR is taught in orgo II at state school and orgo I at my school, so.... yea, i'm screwed on this topic). i'm tryin to read the chapters in my textbook, but i'm not sure what all i need to know for the mcat. any advice?

I TAed O Chem lab and I have always had a soft spot in my heart for NMR.

Id go hit up google with a search string for NMR and Practice Problems, locate some and quiz yourself silly. This is how I studied for the final.

IR is kindof worthless, there are only a few points you need to know that I can sum up:

A broad stretch near 3600 cm-1 is OH
A sharp peak in this region is NH
Locate the 3000 cm-1 mark. A peak to the left of this is indicative of aromatic Hydrogens, to the right of this are aliphatic hydrogens.

1650 - 1700 cm-1 peaks are C=O.

Everything else is worthless.

I agree with Coops. The only way to get NMR is to practice practice practice. and for IR just make a list of major peaks, there is nothing else u can do with it, IMHO.

As far as NMR on MCAT is concerned, they r not going to ask u any super duper difficult question, so if you cover the chapter in your text and understand the material, that will be more than enough.

Hope it helps. 😀

This chapter is pretty easy with little reading you should be able to do fine

This site has some pretty good links to spectroscopy tutorials. hope that helps!

try this:

it is very very helpful.

this is from my university - it is very straightforward.

here is the whole list... look through it and you will find even more things on spectroscopy (in addition to any organic topic you might want to review).

I still think the best way to learn is to read your organic text book. Read the entire chapter, it shouldn't take more than 5 hours to read the whole chapter.
Also for NMR/IR the best way to learn is to do a lot practice problems on the end of the chapter in your text.

I wouldn't take the chance and skip information if I were you.

Sorry to repeat my post, I am heavily biased about this.

Learning NMR is very very easy if you do the following things:

1) Go on UC Irvine's Open courseware lecture series (link bellow) and watch the three lectures on NMR. Lecture 17,18,19:

2) The lectures are not enough. To get a good understanding of the theoretical underpinnings, skim through your text book also.


3) Buy 'Organic Chemistry as a Second Language: Second Semester Topics' by David Klien on amazon.
It's a great book that is very clear and short, and has sufficient practice material. Not too much. Just right.
