CanadianNMR Facility Manager at the University of Manitoba (Dec 15/16)

The University of Manitoba is seeking a full-time Facility Manager for a multiuser Nuclear Magnetic Resonance (NMR) Centre located in the Department of Chemistry at the University of Manitoba. The Centre is equipped with four high-field NMR spectrometers used for a wide variety of research and teaching applications, including solid-state materials chemistry, structure and dynamics of biomolecules, and the structural elucidation of small molecules.

Principal duties will include: operation, maintenance and repair of the NMR spectrometers and associated hardware and software; cultivating a safe, effective and productive laboratory environment; interfacing with a wide variety of users; and managing the billing and financial health of the Centre. The position involves active technical and scientific engagement with internal and external users, daily interaction with undergraduate and graduate students, postdocs and staff in teaching and training capacities. The Manager also supervises an NMR technician who assists with routine spectrometer operation and maintenance.

Expertise in solid-state NMR, advanced multidimensional pulse-programming, hardware development and network management are highly desired. Familiarity with both Bruker and Varian/Agilent NMR systems is an asset. Collaborative research and teaching will be encouraged. A Ph.D. in Chemistry is preferred; however a Ph.D. in Physics or M.Sc. in Chemistry/Physics with at least five years of experience managing an NMR laboratory will be considered.

More information about the position and how to apply may be found at:


Application materials may also be sent to:

NMR-Director.Chemistry "at" umanitoba.ca

Evaluation of applications will begin on 10 January 2017 and continue until the position is filled. Start date: 1 February 2017 or as soon as possible thereafter.

Application materials, including letters of reference, will be handled in accordance with the protection of privacy provision of The Freedom of Information and Protection of Privacy (Manitoba). Please note that curriculum vitae may be provided to participating members of the search process.

The University of Manitoba is strongly committed to equity and diversity within its community and especially welcomes applications from women, members of racialized communities, Indigenous persons, persons with disabilities, persons of all sexual orientations and genders, and others who may contribute to the further diversification of ideas. All qualified candidates are encouraged to apply; however, Canadian citizens and permanent residents will be given priority.

Cover article in Chemical Communications (July 30/09)
chem comm Unique instrumentation available at the 900 NMR Facility allows our users to deal with systems and nuclei inaccessible before with NMR at lower fields. One example is 73Ge NMR in solids which was previously limited only to highly symmetric environments. In this cover article just published by Chemical Communications a research team from the University of Manitoba and NRC-SIMS is reporting natural abundance 73Ge NMR spectra in much more challenging amorphous and crystalline germanium oxides. Work continues on even more complex glasses and crystalline phases to address long-standing fundamental questions in glass science, such as the ‘‘germanate anomaly’’.

SpinWorks 3.1 is available for download (Feb 11/09)

Version 3.1 of the SpinWorks NMR freeware processing and simulation package is now available for download at:


The file is SpinWorks_310.zip

In addition to the usual bug fixes new features include the ability to read and display processed 2D and 3D data from NMRPipe, and a band-fitting (deconvolution) feature. The LP routines have been re-written for .NET so the code is now .NET clean, with the LP.dll Win 32 file no longer needed.

The program should run on all Windows systems from Win 2000 and up, and has been run successfully on Macs with "parallels". Being .NET clean it should also run on Linux under "mono" with all path separator issues ("\" vs "/") being resolved. I haven't been doing any Linux testing myself, so any feedback that I can get would be greatly appreciated!

Scott Kroeker receives provincial funding (Jan 25/09)

Scott Kroeker is among several other researchers from the University of Manitoba to share more than $2.3 million in funding from the Manitoba Government. The funding is provided through the Manitoba Research and Innovation Fund to support research projects related to health, environment and advanced technologies.

SpinWorks (updated November 25, 2008)

Update: SpinWorks 3.1 Beta test version (see below) is now awailable for download at ftp://davinci.chem.umanitoba.ca/pub/marat/SpinWorks/

SpinWorksSpinWorks is a freeware software package for
the processing and display of 1D and 2D data.
Also included are modules for the simulation
and analysis of second order spectra, and
dynamic (exchange broadened) NMR spectra.

While many processing packages seem targeted to the biological NMR community, SpinWorks focus is synthetic organic and inorganic chemists. However, SpinWorks does just as good a job at processing 2D BioNMR data as any other package that I am aware of. An effort has been made to create a coherent easy to follow user interface, and to obtain as much processing information as possible from the data set. For many of 2D experiments, simply clicking the "Process" button is all you need to properly process your 2D data.

These versions of SpinWorks are currently available for download:

SpinWorks 2.5.5 This is a Win32 version that should run on anything from Windows 95 and up. It also runs under WINE on Linux and under assorted Windows emulators on Macs. Supported data formats are Bruke
r (UXNMR/XwinNMR/Topspin) and Varian (VNMR/VNMRJ) for 1D and 2D. Tecmag (1D and 2D) and JEOL (1D only) are supported, but not thoroughly tested. 1D spectra can also be saved and read in JCAMP-DX format. SpinWorks 2 is in maintenance mode (no further development).

SpinWorksSpinWorks 3 Runs under the Microsoft .NET runtime environment. Hopefully it will run on other .NET environments as well, such as the Linux mono package (testing under way). The aim is eventually to have the program platform independent and open source. Fully supported data formats are Bruker (UXNMR/XwinNMR/Topspin) and Varian (VNMR/VNMRJ). JCAMP-DX is supported for 1D only. SpinWorks 3 can also read simulated FIDs and spectra produced by the SIMPSON program.

SpinWorks 3.1 A beta test version of this release will be available very soon (target date: Nov 1, 2008). This release adds the ability to read 2D and 3D processed data from NMRPIPE, Hilbert transforms, and a bandfitting
(deconvolution) feature. This release also addresses a number of issues resulting from the use of “,” instead of “.” as the decimal separator in many parts of the world, and several other upgrades and bug corrections.
