WISE (WIdeline SEparation) is a powder MAS heteronuclear correlation experiment. In the common 1H-13C implementation, molecular dynamics information is contained in 1H line shapes that are separated in the second dimension by 13C chemical shifts. Further information in (https://doi.org/10.1021/ma00038a037).

## Syntax

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

## Arguments

parameters.spins - working spins, e.g. {'1H',13C'} parameters.hi_pwr - amplitude of high power pulses on the high-gamma channel, Hz parameters.cp_pwr - amplitude of CP pulse on each channel during the CP contact time, Hz parameters.cp_dur - CP contact time duration, s parameters.rho0 - initial state parameters.coil - detection state parameters.sweep - sweep width, Hz for F1, F2 parameters.npoints - number of points in F1, F2 H - Hamiltonian matrix, received from context function R - relaxation superoperator, received from context function K - kinetics superoperator, received from context function

## Outputs

fid.sin, fid.cos - sine and cosine components of the States quadrature
