Description

Double-quantum version of the 13C-detected 14N-13C MAS 2D correlation experiment described by Jarvis, Haies, Williamson and Carravetta in http://dx.doi.org/10.1039/c3cp50787d

Arguments

       parameters.spins    - isotopes to which the sequence is applied,
                             specified as a cell array with 14N first,
                             and 13C second

       parameters.spc_dim  - Fokker-Planck spatial dimension

       parameters.sweep    - sweep widths in the two dimensions, Hz

       parameters.npoints  - numbers of points in the two dimensions

       parameters.rho0     - initial state

       parameters.coil     - detection state

       parameters.rf_pwr   - RF power on 14N, Hz

       parameters.rf_dur   - RF pulse duration on 14N, seconds

Outputs

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