rotating-frame NOE spectroscopy

synonym: cross-relaxation appropriate for minimolecules emulated by locked spins (CAMELPSIN)
acronym: ROESY

Measurement method of nuclear magnetic resonance spectroscopy yielding through-space correlations via spin-spin relaxation.
Notes:
  1. ROESY is similar to the NOESY experiment (see nuclear Overhauser effect spectroscopy) and is useful for determining which signals arise from protons that are close to each other in space even if they are not bonded.
  2. ROESY has the advantage over the NOESY experiment that its response does not go through a null at specific correlation times and is thus preferred for molecules having molecular masses of a few thousand Da.
