Cooling overall spin temperature: protein NMR experiments optimized for longitudinal relaxation effects.
In experiments performed on protonated proteins at high fields, 80% of the NMR spectrometer time is spent waiting for the (1)H atoms to recover their polarization after recording the free induction decay. Selective excitation of a fraction of the protons in a large molecule has previously been shown...
