Spin system of strychnine.




The function returns Spinach input structures for the very popular spin system of strychnine, intended as a standard example and test case for NMR pulse sequence simulation. The isotropic chemical shifts and J-couplings are taken from 200 and more NMR experiments: a practical course by Berger and Braun. Coordinates taken as those of the major conformer of strychnine proposed in


    spins - a cell array containing the isotopes to import, e.g. {'1H','13C'}.


    [sys,inter] - Spinach input data structures used by create.m


The following call returns the proton subsystem:



  1. 13C-13C J-couplings are not provided - this file is only suitable for natural abundance 13C simulations.
  2. CSA tensors are not provided - relaxation theory treatments on top of this file would not account for CSA relaxation.
  3. Only shifts and coordinates are provided for 15N nuclei - there are no CSAs or J-couplings.
