A. S. Edison University of Florida 2006 1D NMR I z 90 I x - I y W I t I z (- I y cos ( W I t) + I x sin ( W I t) )* e - ( R 2 * t ) For a single spin and no coupling, a 1D NMR experiment can be described as follows. Recall that the drawing of the FID signifies that the receiver is turned on to record the signal.

A. S. Edison University of Florida 2006 The next step… What happens to the spins if the receiver is not turned on? Just the same thing (they don’t care if you record their signal or not). I z 90 I x - I y W I t I z (- I y cos ( W I t) + I x sin ( W I t) )* e - ( R 2 * t )

A. S. Edison University of Florida 2006 Time to add another pulse I z 90 I x - I y W I t I z (- I y cos ( W I t) + I x sin ( W I t) )* e - ( R 2 * t ) 90 I x (- I z cos ( W I t) + I x sin ( W I t) )* e - ( R 2 * t ) What happens here?
