The equipments are operated by our staff, who ensure that the samples are correctly performed, launch the requested experiments, process the spectra and recover the samples. Interpretations of the spectra are performed only at request and on a collaborative basis.
Users outside the University of Bucharest may have access to all of this instrumentation either via collaboration or with a fee-based agreement.
The infrastructure of the NMR centre is also available to industry at very reasonable cost and with guaranteed rapid throughput.
The 300 MHz spectrometer is available as a permanent user facility. The 500 MHz spectrometer is available upon prior schedule. For more details, please see the contact details.
Users must bring their own deuterated solvents and NMR tubes. The deuteration degree is at the user responsibility and choice, according to the requested experiments. For common NMR experiments, the following solvents are recommended: CDCl3 99.98%, DMSO-d6 99.98%, D2O-99.98%, CD3OD-99.98%, CD3CN-99.98%, CD3COCD3-99.98%.
Quality of the NMR tubes must be at least equivalent to:
- Wilmad, 528-PP-7 (L-7 in., camber 13 μm, concentricity 25 μm, diam. 5 mm)
- Norell NOR508UP7 (L-7 in., O.D. × I.D. 5 mm × 4.2 mm, camber ±0.013 mm, concentricity ±0.005 mm)
- WILM 528-LPV-7 NMR tubes, low pressure/vacuum, 177,8 mm, 25 µm, 13 µm 500 MHz, 5 mm O.D (for air-sensitive samples)
Users are responsible for the cleanliness of the tubes.
The samples must be completely soluble in a deuterated solvent. The quality of the spectra depend on the sample concentration (good quality spectra require a concentration of at least 25-50 mM). The samples will be dissolved in 0.8 – 1.0 mL deuterated solvent.
