A 3D HNCO experiment for two HNCO-spin systems
Pulse Program: HNCO3D (from Bruker) modified to
replace selective shaped pulses on carbon with hard pulses.
Spin System:
consists of two isolated sets of 1H-15N-13CO systems,
with chemical shift positions defined as shown above and the
scalar couplings set to: 1H-15N = 92Hz; 15N-13CO = -15Hz
Graph-representation of the Spin Setup:
Experimental Parameters:
td1=16 (15N), td2=32 (13C), td3=32 (complex) (1H)
