Title: NMR in data book
Post by: shokstar on May 10, 2010, 08:47:59 pm

In the NMR data book, what does a subscript mean? ie. R₃-CH??

Any help appreciated

No idea, but can I ask what you got for ur mid year exam for biology? Like the statement of marks score if you got it

No i didnt get it, but most likely i got a 61-65/75, which is a low A+. For that 42 i got this, a high A+ for SACS and a low A+ for end of year. If i worked that little bit harder, (i took it a little too easy) it couldve boosted my score. SO make sure you have no regrets like me.

3 side chains attached to the carbon

Oh yeh, that makes sense. Carbon needs 4 bonds so therefore 3 side chains plus the H = 4 bonds. Thanks very much
