Anyone that has taken the test recently, would you say there is a lot of the spectroscopy and purficiation & Separation on the Actual DAT
?

I know its good to know it, but how throughly would you recommend knowing it.. like the NMR diagrams and what not and the chemical shift (ppm) values?

I had a separation question on my test, and one or two questions about IR/NMR, so it would be good to know some of the big shifts and values for like alcohols, benzene, carbox acid, aldehyde, ketone, etc.
