The lab consists of four 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), a Varian MercuryPlus 300/54 in Rm. 105 (2003), and a General Electric/Tecmag GN 300/44 in Rm. 106 (1987). The EPR spectrometer is a Bruker EMX in Rm. 170.
Spectrometer Descriptions
The
GN 300 has 2 rf channels, a proton or broadband
channel (300 MHz or 15-125 MHz) and a proton-only channel. It has been upgraded with a Tecmag data acquistion system
and Power Macintosh 8100/80.
The
Varian MercuryPlus 300 can observe H-1, F-19, P-31, and C-13 nuclei and has a pulsed field gradient capability.
The UnityInova 300 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 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.
The Bruker EMX is a continuous wave X-band EPR spectrometer with sample temperature control capability.
Brief Description of Spectrometer Use
The UnityInova 300 and MercuryPlus 300 are used for routine proton, fluorine, phosphorus, and carbon spectroscopy during the day (Inova 300 : Mon.-Fri. 9am.-8pm., Sat. and Sun. 10am.-4pm.; MercuryPlus 300 : Mon.-Fri. 9am.-6pm., Sat. and Sun. 10am.-4pm.) on a short term (15 minutes), first come, first served basis. Longer blocks of time are available during the evenings. The GN300 is currently used primarily for phosphorus experiments and is available for other experiments by request. The UnityInova 500 is used mainly for solution work on large molecules and dilute samples. Requests for large blocks (ie. >15 minutes) of spectrometer time should be made in advance. 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 are used for NMR data processing;the primary processing application is MestReC. MR lab spectrometers and computers are linked to the Internet.
