| Short Description: 400 MHz NMR spectrometer with WB magnet (Ultrashield+), Avance II+ console, three frequency channels, 5 mm ATM-BBFO probehead, 4 mm MAS probehead, BLAXH500/100 and BLAXH300/100 amplifiers | Picture of the Equipment
| |
| Available Experiments/Techniques: high resolution 1D 1H-, 19F- and X- (frequency range: 31P-109Ag) NMR standard experiments and multipulse sequences, selective excitation with shaped pulses, adiabatic pulses, 1H, X-, 19F, X-, 1H,19F- as well as homonuclear 1H-, 19F- or X- 2D correlation spectroscopy. | ||
| Special Equipment: Sample changer BACS 60, frequency range between 15N and 109Ag for high resolution and between 15N and 33S for MAS available, low temperature capable till -140 °C (MAS), both solid state or high resolution measurements possible. Triple resonance probehead for multi-decoupling experiments (since 2013). | ||
| Measurements on the equipment are currently done by: | Students after introduction Students after extensive training Trained scientific service personal | |
