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
0oC or above 50oC
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.
