NMR

We have 6 solution-state spectrometers in operation, all supplied by Bruker. Five of the systems had major updates in 2013 to AvIII HD standard; the sixth is a much older DRX-400. All the systems have multinuclear probes.

• Three Av-400 spectrometers, each with a “SampleXpress” automatic sample changer, provide an open-access “walk-up” service for trained users only.
• One 500 MHz spectrometer and two 400 MHz spectrometers are used to provide a service and primarily run longer or more specialised measurements. These spectrometers each have a rather older version of the sample changer.
• The facility can be used to observe many nuclei, for example ¹H, ²H, ⁷Li, ¹¹B, ¹³C, ¹⁴N, ¹⁵N, ¹⁷O, ¹⁹F, ²⁷Al, ²⁹Si, ³¹P, ³³S, ³⁵Mg, ⁵⁹Co, ⁷⁷Se, ¹¹⁹Sn and ¹⁹⁵Pt. The types of experiments on offer include 2D measurements, COSY, HSQC, HMBC, HMQC, NOESY, ROESY, HOESY, TOCSY and ¹⁹F-X correlation; Relaxation (T₁ and T₂); Diffusion (DOSY); Reaction Kinetics Monitoring and Variable Temperature (-90°C → +120°C).

Potential users of the open-access systems should consult the NMR staff about training. Samples for the service are submitted via room B12: new users should consult the NMR staff for details.

Distribution of data

Data from all these instruments is available via the NOMAD server. An archive of pre-NOMAD data is also maintained on a storage system operated by ICT. This archive can be accessed via a server provided by ICT at icnfs-chnmr-backups.cc.ic.ac.uk\ch-nmr.

Desktop NMR processing software for PCs

The majority of students and researchers are using the MestReNova product for which we have a campus license: it can be downloaded from \\store.ic.ac.uk\ic\fons\chemistry\general\software. Free Bruker Topspin software with a 3-year academic license can be obtained directly from Bruker.

Charging for NMR services

All work is charged based on the machine time used: we charge at the same rate for each instrument. The hourly charges as of October 2024 are as follows:    

• Chemistry Department users (FEC grants) £12
• Other Imperial College users £15
• External to the College £70 (+ ICON fee) 
• External users should contact Imperial Consultancy (ICON)
• https://www.imperial-consultants.co.uk/services/
