Insensitive: Simulation of the NMR Experiment for Didactic Purposes

Since its first publication in 2011, the program "Insensitive" has progressed to be one of the most feature-rich, educational simulation tools for the nuclear magnetic resonance experiment in homogeneous solution. It can be used without prior knowledge of a programming language or complex spectrometer software. In four steps it follows the spin physics behind NMR, from the creation of a spin system to the acquisition and processing of a one or two-dimensional spectrum. At its core, it visualises common models of the spin state, both graphic and numerical, and allows to manipulate each interaction at various levels of sophistication. Thus, it provides graphical aides and can be used as a tool for teaching and self-teaching a highly abstract and demanding topic.
