NMR Simulator
NMR spectroscopy becomes quickly difficult to predict when second order simulation is observed. Here you can simulate the problems by entering the spin system you want to simulate, the chemical shift as well as the coupling constant.
You will obtain a 400 MHz simulated spectrum.
This project is the result the collaboration of Julien Wist (University of Cali, Colombia), Andres Castillo (University of Bogota, Colombia) and Luc Patiny (Ecole Polytechnique Federale de Lausanne, Switzerland).
