NOESY (Nuclear Overhauser Effect
SpectroscopY
):
A
2D-NMR
technique utilizing the
nuclear Overhauser effect
. When a nucleus (usually a
proton
)
relaxes
from an
excited
nuclear spin state
to its
ground
nuclear spin state
the energy may be transferred to another nucleus in the
molecule
; this is called the
nuclear Overhauser effect
. The NOESY
spectrum
reveals which
protons
are close enough (usually no more than about 3
Angstroms
apart) to transfer energy this way.
