# roesy.m

From Spinach Documentation Wiki

Phase-sensitive homonuclear ROESY pulse sequence, assuming ideal spin-lock.

## Syntax

fid=roesy(spin_system,parameters,H,R,K)

## Arguments

parameters.sweep - a vector with sweep widths in F1 and F2 directions, Hz parameters.npoints - a vector with point count in F1 and F2 directions parameters.spins - nuclei on which the sequence runs, e.g. {'1H'} parameters.tmix - mixing time, seconds H - Hamiltonian matrix, received from context function R - relaxation superoperator, received from context function K - kinetics superoperator, received from context function

## Outputs

fid.cos, fid.sin - components of the free induction decay for hypercomplex processing

## Examples

ROESY simulation for strychnine (examples/nmr_liquids/roesy_strychnine.m) appears below.

## Notes

Analytical spin-lock is an approximation.
