NMR meets MUSICIANS


1. General Overview

This page and the linked sub-pages will introduce to you the auditory presentation of free induction decay (FID) signals obtained by NMR spectrometers (NMR=Nuclear Magnetic Resonance). Usually, NMR spectrometers work in a silent mode. However, due to the fact that the results they produce are in the audio frequency range, acoustic monitoring is possible as well.

It will be demonstrated in this article how such audio monitoring may extend the information contents of pure optical presentation, thus being an aid in structure analysis. In addition, by appropriate pulse programming it is possible to play melodies on an NMR spectrometer. The underlying pulse sequences are acronymed "MUSICIANS". Go and learn about this mysterious abbreviation.

All spectra shown subsequently and all sounds/melodies were obtained on a JEOL Alpha500 NMR spectrometer at the NMR department of the Institute of Organic Chemistry of the University of Erlangen-Nuremberg, Germany. Spectrum recording, hardware modification and song writing was done by Walter Bauer.
