NMR spectra of Macromolecules and small molecule
Spatial folding : different NMR chemical shifts derived from different environments
Labile protein : slower exchange rate than intrinsic exchange rate
Different relaxation properties :
1) Brownian motion (diffusion) : spin relaxation , NOE
2) spin relaxation : rotational tumbling , Tc (correlation time) is related to size of molecule
(1) 1/Tc ∞ molecular size : small – fast , big – slow
(2) small molecule : narrow line shape
(3) big molecule : broad line shape
