Abstract
The home-built pulsed nuclear magnetic resonance spectrometer is described, it consists of rather cheap commercial hardware for radio frequency (RF) pulse generation and signal acquisition system. The old-stuff superconducting magnet (9 T) and modified current insert allows to vary first order cold shim gradient fields and the B0 field in the range of 0-8.5 T. The helium cryostat inserted in a wide bore of the magnet and the sample temperature control system allow to perform nuclear magnetic resonance (NMR) experiments in the temperature range of 1.65-300 K. The software created in Labview development environment synchronizes the RF excitation and acquisition systems and controls the parameters of pulse sequences and data acquisition in the 5-500 MHz range of frequencies. The maximum achieved resolution in 1H NMR spectra using first order cold shims is ca. 0.5 ppm in a spherical water sample of 5-mm diameter.
