COSY , COSYDQF , Long-range COSY
COSY
This technique allows to observe a pulse spin-spin interaction constant of less than 1 Hz. This example shows the interaction of the aldehyde proton (17) and the protons of the methylene group (18,19) with the protons of the benzene ring.
LONG RANGE COSY
NOESY..........Correlation protons located close in space.
