Zero-field NMR with an abrupt field drop.
Syntax
fid=zulf_abrupt(spin_system,parameters,H,R,K)
Description
Zero-field magnetometry experiment that propagates the initial condition through an exponential drop in the external magnetic field and then runs the detection at zero field.
Arguments
parameters.drop_field - the magnetic field that the sample should
be dropped to, starting from the field spe-
cified in sys.magnet, Tesla
parameters.drop_time - drop time, seconds
parameters.drop_npoints - number of discretisation points in the drop
parameters.drop_rate - field drop rate, Hz
parameters.rho0 - initial state
parameters.coil - detection state
parameters.sweep - sweep width during acquisition
Outputs
fid - the free induction decay detected on the
coil state supplied
Examples
See zero_field_acetonitrile.m file in examples/nmr_zerofield directory.
