Budker group style gamma-weighted pulse-acquire sequence in zero field. The pre-polarisation magnet at high temperature followed by a pulse are emulated by summing up L+ states with the weights equal to the magnetigyric ratio of each spin.
Syntax
fid=zerofield(spin_system,parameters,H,R,K)
Arguments
parameters.sweep - the width of the spectral window (Hz) parameters.npoints - number time steps in the simulation H - Hamiltonian matrix, received from context function R - relaxation superoperator, received from context function K - kinetics superoperator, received from context function
Outputs
fid - free induction decay
Examples
Multiple examples are avilable in examples/nmr_zerofield directory. ZULF simulation for pyridine, matching Figure 3 from http://dx.doi.org/10.1021/ja2112405, is reproduced below.
