Predefined experiments

This gives a comprehensive summary of the available predefined experiments and their parameters available to saffron and spidyan. They can be accessed through the Exp.Sequence field.

If any of the below sequences is used in combination with the thyme algorithm , standard monochromatic rectangular pulses are assumed with a length of 16 ns for a 90° pulses and 32 ns for a 180° pulses.

2pESEEM
Minimal call: 
Exp.Sequence = '2pESEEM'
Exp.dt = 0.01; % time increment in microseconds

Exp.dt
Time increment (dwell time), in microseconds.

The following fields are optional in combination with Exp.Sequence = '2pESEEM'

Exp.tau
This is the starting τ value. If omitted it is set to zero. Has to be non-zero if used with the thyme algorithm.
Exp.nPoints
Number of data points along the indirect dimension, default is 512.
3pESEEM
Minimal call: 
Exp.Sequence = '3pESEEM'
Exp.dt = 0.01; % time increment in microseconds
Exp.tau = 0.1; % tau in microseconds

Exp.dt
Time increment (dwell time), in microseconds.
Exp.tau
Value of τ, in microseconds.

The following fields are optional in combination with Exp.Sequence = '3pESEEM'

Exp.T
The starting T value, in microseconds, default is 0.
Exp.nPoints
Number of data points along the indirect dimension, default is 512.
4pESEEM
Minimal call: 
Exp.Sequence = '4pESEEM'
Exp.dt = 0.01; % time increment in microseconds
Exp.tau = 0.1; % tau in microseconds

Exp.dt
Time increment (dwell time), in microseconds.
Exp.tau
Value of τ, in microseconds.

The following fields are optional in combination with Exp.Sequence = '4pESEEM'

Exp.T
The starting T value, in microseconds, default is 0.
Exp.nPoints
Number of data points along the indirect dimension, default is 512.
HYSCORE
Minimal call: 
Exp.Sequence = 'HYSCORE'
Exp.dt = 0.01; % time increment in microseconds
Exp.tau = 0.1; % tau in microseconds

Exp.dt
Time increment (dwell time), in microseconds.
Exp.tau
Value of τ, in microseconds.

The following fields are optional in combination with Exp.Sequence = 'HYSCORE'

Exp.t1,Exp.t2
The starting values of t1 and t2, in microseconds.
Exp.nPoints
Number of data points along the indirect dimensions, default is 128 for both dimensions. The indirect dimensions can have different lengths: 
Exp.nPoints = [128 64]; % 128 points along first dimension, 64 along the second
MimsEndor
Minimal call: 
Exp.Sequence = 'MimsEndor'
Exp.Range = larmorfrq('1H',Exp.Field) + [-1 1]*10;
Exp.tau = 0.1; % tau in microseconds
Exp.tau
This gives the value of τ, in microseconds.
Exp.Range
Contains lower and upper limit of the frequency range for ENDOR. Values should be in MHz, e.g. Exp.Range=[0 30].
