ANTIOPE, a program for computer experiments on spin dynamics

Abstract ANTIOPE is a self-contained program, running on personal computers, for simulating a variety of real and hypothetical NMR experiments. Systems of up to five spins with fixed or anisotropic truncated Hamiltonians can be subjected to time-varying external fields of arbitrary amplitudes, frequencies, and phases and to the effects of random motions and sample rotations. The resulting 1D and 2D data sets can be manipulated and plotted interactively. No conventional programming skills are required: the program interacts with the user in NMR terms and provides extensive prompting, error trapping, warning facilities and context-sensitive help.
