δ= (υobs-υref)/υrefx 106
position in spectrum is determined by the chemical environment
alkyl group
peak intensities depend on the number of contributing nuclei
•Coupling
•peaks have a fine structure related to the presence of neighbouring nuclei
approx. 7 Hz in alkyl groups
through bond coupling - scalar coupling
1/2 nuclei will appear as a series of n+1 lines where the separation of those
lines is determined by the coupling constant J and the relative intensity of the
lines are determined by Pascal’s triangle:
