Phase-sensitive NOESY-HSQC sequence from
using the bidirectional propagation method described in
The sequence is hard-wired to 1H,15N,1H. Syntax:
where H is the hamiltonian commutation superoperator, R is the re- relaxation superoperator and K is the chemical kinetics superope- rator. The output has four fields
fid.pos_pos, fid.pos_neg, fid.neg_pos, fid.neg_neg
that are used in the subsequent States quadrature processing. The following parameters are required:
parameters.npoints - a vector of three integers giving the number of points in the three temporal dimensions, ordered as [t1 t2 t3].
parameters.sweep - a vector of three real numbers giving the sweep widths in the three frequen- cy dimensions, ordered as [f1 f2 f3].
parameters.J - J-coupling for the HSQC stage magneti- zation transfer, Hz.
parameters.tmix - NOESY stage mixing time, seconds.
Frequency dimensions: F1 is 1H, F2 is 15N, F3 is 1H, carbon is de- coupled throughout.
