Center for NMR Spectroscopy
The Center for Nuclear Magnetic Resonance(NMR) Spectroscopy at Baylor functions through a collaboration between the departments of Chemistry & Biochemistry, Geosciences, and the Director's Office of the Sciences Building. For routine training and access to the instruments, please contact the NMR teaching assistant (Graham Carlson, Graham_Carlson@baylor.edu). For all other issues and advanced training, contact Dr. Xu (See contact information on the right). See below for a description of available instrumentation and for Facility Policies.
The Center for NMR Spectroscopy contains five NMR’s including three high resolution instruments, including an Agilent VNMRS 500 MHz NMR equipped with multinuclear and variable temperature capabilities, a Bruker Fourier 300 MHz (Probe: 5mm DUL 13C-1H-D with z-gradients) for 1H and 13C analyses to support undergraduate teaching, a Bruker Avance III HD 400 MHz with mutlinuclear (5mm PABBO BB(31P-109Ag)/19F-1H-D probe with z-gradients) and variable temperature capabilities, a Bruker Avance III HD 600 MHz with multinuclear and variable temperature capabilities as well as a Prodigy Cryoprobe(CPP BBO probe).
Access to Labs and Instruments
- Instrument training by the NMR Graduate Teaching Assistant is a prerequisite to using any of the facility instruments. Note that special training is required for the solid state NMR, which is administered by Prof. Bill Hockaday.
- Instrument accounts will be created at the time of training. Be sure to ask for accounts to be created on any additional instruments you will need to access (e.g., you may access both the Bruker Avance III HD 400 and 600 MHz instruments as well as the Bruker Fourier 300 if you have been trained on the 600).
- Card-access forms may be signed by either the NMR Graduate Teaching Assistant or by Dr. Xu once training is completed. Note, Dr. Xu can only sign your form if he is aware that you have been trained.
- Prior laboratory safety training through Baylor University's Department of Environmental Health & Safety is mandatory.
- NMR Time for each instrument may be reserved using the Baylor Facility Online Manager(FOM). Permitted sign-up times are posted above each instrument's FOM Schedule and should be respected.
- Instructions on how to sign up FOMs can be found in the NMR Documentation page.
- Any experiments that need special considerations or allowances should be cleared first by Facility personnel.
- You must sign up the FOM schedule before setting up any analysis.
- You are required to legibly label your NMR tubes with at least your initials on the glass or the cap with a permanent marker. No physically attached labels or alternate marking strategies are permitted.
- Tape, parafilm, or other materials must not be attached to the sample tubes.
- Sample rotation is not permitted without special permission on any instrument except the Bruker Fourier 300. Samples must never be rotated on the Bruker Avance III HD 600.
- Several of our instruments have autosamplers that enable unattended runs. You are responsible for promptly removing your NMR tubes from both the NMR sample changer and the NMR Laboratory. It is expected that you will remove samples within 30 minutes during peak hours and by 9:00 AM the next day for overnight runs.
Failure to follow the specified policies can result in loss of NMR privileges, which may include disabling automated data delivery or loss of facility access (depending on the severity of the problem and whether or not you are a repeat offender). Please understand that these policies are required to maintain a safe and efficient working environment.
