Insensitive simulates the quantum mechanical models that are used to describe the nuclear magnetic resonance (NMR) experiment. The vector model, density matrix and product operators of an ensemble of up to four spins-1/2 and two spin types are visualized. Each step from the first radiofrequency pulse to the acquisition of the spectrum can be manipulated. Features include selective pulses, weak and strong coupling, dipolar relaxation, gradients, cartesian and spherical product operator basis, phase correction, pulse sequence recording and a comprehensive tutorial.
To make full use of this app a basic knowledge of quantum mechanics as well as a textbook on NMR is recommended.
Check out the free Mac OS X version of Insensitive at http://www.chemie.uni-hamburg.de/nmr/insensitive, which includes the capability to acquire 2D spectra.

You study chemistry? You use NMR? You need to try this app!
The author has put very much effort into this app to visualize NMR-experiments.
Therefore, if you study chemistry or nature science and work with NMR and got problems with understanding the theory, try this app.
This app visualises the spin and also coupling and furthermore.
I don't think, that there is any app comparable at the moment.
I reckon this is the most powerful educational app out there, considering the content it deals with and the overall execution of the aim behind developing it. Kudos, and thank you.
Fun with NMR!
Thank you for a sweet little app that nobody else has done!
