24 Feb 2004: Under these circumstances the offset, , is zero and so the reducedfield, B, is also zero. ... 3.10 Relaxation 3–15. xy y. z. B1. x. z. B1. (a) (b).

24 Feb 2004: modulation in t1 can be expanded, using the formula,cos sin sin sinA B B A B A= ( ) ( ){ }12 to give. ... If two two-dimensional multipletsappear at (F1, F2) = (A B, A) and (A B, B) the implication is thatthe two spins A and B are coupled, as it is only

24 Feb 2004: Fouriertransformation of S(t) gives the spectrum S(ω):. S B A Dω ω ω( ) = ( ) ( )[ ] ( )i iexp Φ [1]. ... Re cos sinS B A Dω ω ω( )[ ] = ( ) ( )[ ]Φ ΦIn general this is a mixture of the absorption and dispersion lineshape.
