UVA Chem. Dept. Magnetic Resonance Lab Description

The lab consists of three NMR spectrometers, one EPR spectrometer, and several computers for data processing and lab management.

NMR spectrometers include a Varian UnityInova 500/51 in Rm. 105 (installed 1997), a Varian UnityInova 300/54 in Rm. 106 (1997), and a Varian MercuryPlus 300/54 in Rm. 105 (2003). The EPR spectrometer is a Bruker EMX in Rm. 170.

Spectrometer Descriptions

The Varian MercuryPlus 300 (Ireland) can observe H-1, F-19, P-31, and C-13 nuclei and has a pulsed field gradient capability.

The UnityInova 300 (Lutz) has one full band rf channel ( 300 MHz and 125-30 MHz), one H-1 channel, and a pulsed field gradient capability.

The UnityInova 500 (Burger) has two full band rf channels (each can generate 500 MHz and 210-15 MHz), one low band rf channel (210-15 MHz), a pulsed magnetic field gradient capability, and two waveform generators.

All NMR spectrometers have sample temperature control capability and set up to routinely operate in the range of temperatures from 0 to 50 Celcius. If you need to work below 0^oC or above 50^oC contact Yana Goddard.

The Bruker EMX is a continuous wave X-band EPR spectrometer with sample temperature control capability.

Brief Description of Spectrometer Use

The UnityInova 300, UnityInova 500 and MercuryPlus 300 are used for routine proton, fluorine, phosphorus, and carbon spectroscopy during the day during routine hours on a short term (15 minutes), first come, first served basis. Longer blocks of time are available during the evenings. The UnityInova 500 is used mainly for solution work on large molecules. Requests for large blocks (ie. >15 minutes) of spectrometer time should be made in advance using nmrreq program on ernst.chem.virginia.edu. See Instrument Use Policies for more complete information on spectrometer scheduling and use.

Computer Descriptions

A Sun Ultra 10 (ernst.chem.virginia.edu) is located in Rm. 106 and used for spectrometer scheduling and data storage. Two PC's located in Rm. 106 and 105 are used for NMR data processing; the primary processing application is MestReC. If you need the campus license for MestReC, contact the NMR Lab manager.  NMR lab spectrometers and computers are linked to the Internet.
