NMR Core Facility

The NMR Core Facility at the Faculty of Chemistry and Pharmacy was established in 2025. The facility offers access to five solution-state NMR spectrometers: three open-access NMRs (400 MHz, 400 MHz, and 500 MHz) and two high-field NMRs with restricted access (600 MHz and 700 MHz, both equipped with cryoprobes).

We support researchers by providing access to state-of-the-art, high-resolution NMR spectrometers. Understanding the molecular structures of small molecules derived from chemical synthesis or natural sources, and their biomolecular targets (proteins, nucleic acids) is critical in various scientific fields. NMR spectroscopy is a powerful method for characterizing such entities and their interactions, providing insights into the constitution, conformation, and dynamics of low and high molecular weight molecules.

The NMR Core Facility is open for scientific collaborations within the University and scientific and industrial cooperations with external organizations.

Current activities at the NMR Core Facility include:

  • Structural characterization of end products and intermediates from total synthesis
  • Structural validation of natural products
  • Structural characterization of transition metal complexes
  • Structure & interactions of drug candidates and intermediates
  • Structural characterization of nucleic acid building blocks
  • Biomolecular NMR: Characterization of protein and nucleic acid structure and dynamics

OUR SERVICES

Do-it-yourself NMR

Three open access NMRs - 400 MHz Mars, 400 MHz Ares and 500 MHz Venus - are available for our users. Routine NMR experiments are run in a fully automated fashion. Reservations are not necessary, and routine short-duration data (< 20 min.) are acquired on a first-come-first-served basis, amended by night queue acquisition for experiments on more dilute samples.

Our automated systems are currently equipped to acquire 1H and a wide range of heteronuclei including 13C, 15N, 31P, 19F, 11B, 29Si, 125Te, 77Se, 7Li and 195Pt with the option of 1H decoupling. Other nuclei between 109Ag and 31P frequencies can be added upon request. The systems are set up to acquire No-Deuterium NMR experiments in protonated solvents in full automation.

Variable temperature experiments (-80°C to +100°C) can be scheduled upon request (see section Contact).

Restricted access NMR

Two high field NMR operating at 600 MHz (Jupiter) and 700 MHz (Saturn) are available. These NMRs are run by trained operators and samples can be submitted.



Guidelines

  1. All samples must be supplied in a precision 5 mm tube (e.g. Norell 508UP) to give highest spectral quality. Cracked, scratched or broken tubes will not be accepted! 
  2. The maximum solvent depth for 5 mm tubes should be 4.5 cm (600 µl), the minimum is 4.0 cm (500 µl).  
  3. Run a 1H-NMR spectrum of your sample on one of the three open access NMRs (Mars, Ares or Venus). 
  4. Download the submission form as pdf (see below).
  5. Label NMR tube, fill out sample submission form. Attach a 1H-NMR spectrum from one of the open-access NMRs to this sample submission form. This is mandatory! We reserve the right to reject samples if the sample quality is too low.
  6. Leave NMR tube and submission form in lab L.02.040.
  7. Sample can be picked up in L.02.040 after measurements. NMR data is made available via data servers.


To submit samples for one of the two high field NMRs (Jupiter and Saturn) download and fill in the Submission Form (PDF).
