From the developer:
WSolids1 is a program for the visualization and analysis of processed one-dimensional solid-state NMR data. Although there are several ”general purpose” programs or libraries available to calculate many interactions and for many different experiments, there is still room for programs with specially designed specific calculation models. The main reason is efficiency.
