A question about NMR spectroscopy delta?
 

How do I find the delta for hydrogens? For example, a peak is between 7 and 8. How do I find the exact chemical shift delta?I searched everywhere on how to calculate it but I don't get the same delta of 7.39.

Depending on how advanced of a course you're taking, your text should have a series of equations and tables that allow you to calculate delta's by incremental additions and subtractions of various shielding and deshielding effects (they should be pretty clearly marked in your text). That's pretty advanced, however. More usual is just to recognize that the chemical shift falls into a range - between 7 and 8 means it's an aromatic C-H, for example - and not worry about the precise numbers. Even advanced users don't use precise values of chemical shifts much - there's usually plenty of other information available to allow you to solve a structure.

Perhaps the best method is to count it yourself. It will be difficult to find the delta.Use this to find your molecule.http://riodb01.ibase.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi<br />
