spins 1/2 in isotropic solution. In four steps the program simulates the spin physics behind NMR experiment, from defining the spin system via manipulation of the spin state and execution of pulse sequences [...] models of the spin state, both graphic and numerical, and allows to interact with them at various levels of sophistication. In addition to the statistical quantum mechanics of the system, the double cone [...] cone of a spin 1/2 under the influence of a magnetic field can be shown to illustrate the transition from a single spin to a spin ensemble. The program comes with an extensive tutorial and no prior knowledge
