The TopSpin software by Bruker is used to control the operation of all the NMR spectrometers in the laboratory.

On spectrometer terminals, it is used for both data acquisition and processing; on other computers a processing-only version may be used. It is capable of processing 1D, 2D and 3D data sets and has additional modules for analysis of system dynamics including relaxation and diffusion behaviour.

We recommend TopSpin primarily for those who have been trained in the manual, hands-on operation of our instruments and therefore have some familiarity with the programme. In general, we recommend that new usersuse the Mnova software for data processing on their laptops.



The processing-only version of TopSpin (Windows/macOS/Linux) is free for academic use. You can download this at: You will need to create an account first; once this is done, you will be able to download the software and request an academic license.

During the installation, you will be prompted for an ‘NMR administrator password’. For the processing-only version of TopSpin, this password is generally not important (it is mainly used for configuring attached spectrometers).


Unable to access data on macOS?

There is a known issue with TopSpin on recent macOS versions (10.15 onwards) which makes it impossible to access NMR data stored in some locations. See this guide for a workaround.



There are a number of TopSpin handouts (covering both acquisition and processing) at the handouts page.
