Zerofield.m

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.
