Chemical exchange
From NMR Wiki
Intermediate Exchange: k ~|Insertformulahere1-2|-The exchange rate is approximately equal to the difference in resonance peak positions. Fast Exchange: k >>|Template:Greek Alphabet1-2|-The exchange rate is much greater than difference of resonance peak positions (same units as above). Slow Exchange: k << |1-2|-The exchange rate is much less than the different resonance location (in per second or Hertz).
