600 MHz Bruker Avance lll HD (NMR-600-a)
Bruker ultra-shielded standard-bore magnet equipped with a 5-mm cryogenically cooled 13C/1H DCH probe head for 1H and 13C NMR spectroscopy, but experiments with a range of other probes are also possible. The instrument is equipped with an easy accessible Bruker SampleCase autosampler with 24 positions, which makes unattended around-the-clock operations possible. All operations are controlled by Bruker IconNMR, and users submit samples, select type of experiments, changes parameters if needed, and queue the samples for automated analysis. Data are automatically sent to the user by e-mail and uploaded to an internal file server.

" NMR-spectra were acquired using an 600 MHz Bruker Avance III HD equipped with a cryogenically cooled 5 mm dual probe optimized for 13C and 1H. Samples were dissolved in methanol-d4 (Sigma-Aldrich, 99.8 atom % D) and analyzed at 300 K. Proton spectra, at 599.78 MHz, were acquired using 30°-pulses, a spectral width of 12 kHz, collecting 16 scans with a length of 65536 data points with a relaxation delay of 1.0 sec. FID's were zero-filled to twice the size and exponentially multiplied with a line broadening factor of 0.3 Hz before Fourier transform. Carbon spectra were acquired at 150.82 MHz with 30°-pulses, a spectral width of 36 kHz, collecting 256 scans with a length of 65536 data points and with a relaxation delay of 2.0 sec. The 13C nuclei were 1H-decoupled using the Waltz-16 composite pulse decoupling scheme. FID's were exponentially multiplied with a line broadening factor of 1.0 Hz before Fourier transform"
