The latest release of TopSpin® software, 4.1.3, features a new, user-friendly GUI which provides easy access to vast experiment libraries including standard Bruker pulse sequences and user generated experiment libraries for both industrial and academic users. The GUI enables users to build and organize their own customized experiment libraries via simple drag and drop, provides multiple options for experiment setup and optimization, enables script based parameter adjustment, and makes the setup of sophisticated experiments simple and efficient. For users who must be compliant with the GxP regulations, the software supports the multiple principles of data integrity.
TopSpin offers a fully workflow-oriented user interface and exploits the latest 64-bit features of modern Windows / CentOS / macOS operating systems for optimum memory usage. Both its new workflow-oriented and intuitive user interface and optimized sample data management deliver a long list of additional innovative features, all designed to speed up operation and sample analysis throughput for higher cost efficiency.

Experiment Selector – Intuitive acquisition setup
Topspin contains hundreds of predefined experiments (parameter sets). The most important of these are available in the integrated Experiment Selector.
The parameter sets have been categorized and displayed as a tree. This combines the required flexibility and ease of use. Only one mouse click is required to prepare an experiment based on the selected parameter set.
The spectrometer user can create their own personal selector that matches their own preferences.
Non uniform Sampling
Non Uniform Sampling (NUS) is a fully integrated acquisition and processing feature since TopSpin 3.0. It allows routine use and is available for to all kinds of NMR experiments. An automatically generated and optimized NUS sparse list defines the sampling pattern leading to the fractional data acquisition. Multi-dimensional decomposition then allows to calculate the missing data points enabling a regular Fourier Transform processing of the complete data set, all done in a fully automatic fashion.
NUS removes a time barrier for high-resolution multidimensional NMR spectroscopy and is especially useful for multi-dimensional experiments in biomolecular NMR, where time savings up to a factor of 4 in 3D experiments or 10 and even more in 4D and 5D experiments can be achieved. With NUS, new protein structure determination experiments now become feasible.
Small molecule applications based on 2D spectra can also benefits from an accelerated acquisition by a factor of 2. Of special interest here are improvements in spectral resolution and quality delivered by NUS without the need to increase the overall acquisition time.
The setup and execution of NUS experiments is covered by the TopSpin license. This includes also the processing of 2D spectra. Processing of 3D – 5D NUS spectra requires additional license.
NUS implementation in TopSpin results from a research collaboration with Prof. Orekhov and co-workers. NUS in TopSpin 3.0 benefits from proven algorithms and programs such as NUS-Sampler and MDDNMR (Orekhov, V.Y., I. Ibraghimov, and M. Billeter, J. Biomol. NMR, 2003. 27(2):p. 165-173)
Comparison of 2D HSQC spectra acquired using traditional sampling and NUS. The NUS spectrum on the right side has 4 times better resolution and the experiment was 4 times faster compared to the uniform sampled spectrum on the left side
Advanced acquisition tools
Topspin includes rich set of tools supporting the setup and design of experiments using shaped pulses. New waveforms may be designed and their behavior visualised.
Topspin processing license is free for academia. This includes several tools supporting the understanding of NMR experiments and the analysis of the acquired data
NMRSim is a fully featured simulator of 1D and 2D NMR experiments. The standard Bruker pulse programs are interpreted and the NMR experiment is simulated step by step in the same way as it is executed on a real spectrometer. The result is standard Bruker data set, which is processed in the same way any Bruker NMR data set. The simulation supports also selective pulses and magnetic field gradients.
This allows to use NMR-Sim as a virtual NMR spectrometer both for education or science.
The Topspin license for academia includes the licenses for the CMC ClassRoom software edition. These tools allow to learn basic workflows for small molecules verification and elucidation.
