NMR

The NMR facility in the Chemistry Department houses four high resolution NMR (New Bruker Avance Neo 600 with cryoprobe, New Bruker Avance Neo 400, Varian Unity Inova 400 and Bruker Avance 300.)

In addition, the Department has full access to a Bruker 500 MHz NMR in the Coordinated Instrumentation Facility (CIF).

The Bruker 600 NMR (with cryoprobe) can efficiently collect data for 1H, 13C, 15N, and 31P, offering superior time savings for NMR experiments.  The other instrument can acquire any nucleus from 109Ag to 31P as well as 1H and 19F, at temperature from -80 °C to 150 °C.  The Bruker Avance 300 and Varian 400 are controlled by Linux Centos operating workstations, while the new Bruker Avance NEO 600 and 400 is controlled by Windows operating workstation.  Both of these instruments can be operated remotely and can automatically acquire any randomly sequential or batch 1D and 2D NMR data for up to 24 samples.

All workstations are networked making them easy to transfer data or finished spectra to students' lab computers for inclusion in reports, papers and dissertations.  Mnova NMR PC software is fully access for all users.   About 65 Faculty, staff and students from Tulane, Loyola and Xavier Universities use this facility.
