Influence of Heteronuclear NOE

Optimization of the l/(2V( Sn, H)) delay is more tricky for H- Sn than for H- C HMQC experiments because of the much wider dispersion in y( Sn, H) coupling constant values. These couplings usually range from 0 to more than 200 Hz for organotin compounds. 

6 DEALING WITH THE LARGE Sn SPECTRAL WIDTH IN 2D HMQC EXPERIMENTS 

The resolution in the indirectly detected heteronuclear dimension (F ) depends on the number of increments of the evolution delay, i.e. the number of free
