The NMR laboratory of the Chemistry Department, University of Aveiro, was created in 1993 with funds from the National Science Foundation (FCT) (programme CIENCIA). The facility was upgraded in 2000, 2007 and 2013 with grants from FCT and the national programme POCI 2010, as well as with funds from the Portuguese Centro Region (‘Programa Operacional Regional do Centro, +CENTRO’, through FEDER). Aveiro NMR laboratory has pioneered in Portugal the field of solid-state NMR. At present, it is among the best equipped facilities in Iberia to conduct solid-state NMR studies in the fields of Chemistry and Materials Science. The NMR laboratory encompasses 6 spectrometers, 3 of which are entirely dedicated to the study of solids.
WebpageAbout Nuclear Magnetic Resonance
1D and 2D solid-state NMR spectra of spin 1/2 (1H, 13C, 15N, 29Si, 31P...) and quadrupolar nuclei (2H, 11B, 17O, 23Na, 27Al...).
1D & 2D NMR spectra using MAS, CP/MAS, MQMAS, STMAS (quadrupolar nuclei) and pulse schemes to probe internuclear proximities (REDOR-like recoupling and DQ-SQ spectroscopy). Equipment available: 400 MHz WB, 700 MHz SB; wide-line probes and double and triple-resonance probes for observation of a wide range of nuclei and spin-pair combinations; MAS rates up to 65 kHz.

Terms and Guidelines for accessing solid-state NMR service
1. ssNMR service can only be used by members of CICECO - Aveiro Institute of Materials. If you are not a member of CICECO, please contact us.
2. Fill in all the required fields in the ssNMR booking form and deliver the samples on the very day. Any other information should be conveyed by telephone (967473368, extension 90115).
3. Leave your samples on the table located in the Chemistry Department, ground floor (close to the X-ray diffraction room 15.1.8). Please label the samples with your name and a reference. Protect the labels with scotch tape, or other, so that the sample holders can be cleaned with alcohol.
4. The scheduling of the ssNMR experiences will be shown in the calendar below.
5. Spectra will be e-mailed. Samples will be returned on the same table you left them in first place. Alternatively, you can e-mail or phone and arrange differently.
6. Data processing is of responsibility of each user and can be imported into different viewing programs such as Dmfit (free) or Mnova NMR.
7. Submission of another form is allowed only after completing the previous analyses.
8. All publications with NMR results collected in the NMR spectrometers of University of Aveiro must include the following acknowledgment:
“The NMR spectrometers are part of the National NMR Network (PTNMR) and are partially supported by Infrastructure Project Nº 022161 (co-financed by FEDER through COMPETE 2020, POCI and PORL and FCT through PIDDAC).”
Calendar
If you are not a member of the University of Aveiro, contact us (dq-rmn@ua.pt) with your enquire. Routine solid-state NMR experiments are charged at 75 €/hour (academic institutions). This price does not include discussion of the results, only recording and supplying the spectra. Less trivial spectra will be charged as agreed with us.
The solid-state NMR laboratory of the University of Aveiro is a partner in a running EU funded 4-year project that aims to bring together and integrate 7 national infrastructures across Europe and 1 from the US (PANACEA: Pan-European Solid-State NMR Infrastructure for Chemistry-Enabling Access, 5 M€, https://panacea-nmr.eu). The goal is to open up our laboratories to European researchers from academia and industry, granting them swift access to world-class solid-state NMR research infrastructures. The European Chemical community will, thus, have access to both CICECO’s solid-state NMR equipment and to our specialized knowledge on the application of NMR to chemistry and materials science problems. This project will be coordinated by Mariana Sardo, Luís Mafra and João Rocha.
