NMR Facility

Department of Chemistry
Louisiana State University

The NMR Facility at Louisiana State University houses five high-resolution and one solid-state spectrometer. The high-resolution spectrometers include a Bruker DPX-250, a Bruker AV-400, a Bruker DPX-400 a Varian INOVA-500 and a Varian VS-700. The solid state instrument is a 3-channel Bruker AV-400. All instruments are equipped with Z-axis gradients. The VS-700 spectrometer is equipped with an HCN, triple resonance, cold probe. The DPX-250, AV-400, and the DPX-400 instruments are used primarily for short experiments on a walk-up basis. The 500 MHz and 700 MHz instruments are used primarily for relaxation time measurements, diffusion studies, HR-MAS, and two-dimensional NMR experiments. All spectrometers are controlled by Linux workstations and networked to facilitate the data transfer to an investigator's personal computer for inclusion in manuscripts, and dissertations or for off-line processing. The facility is managed by two spectroscopists, Dr. W. Dale Treleaven and Dr. Thomas Weldegheorghis.
