Introduction
The NMR Facility is a service and research laboratory operated
by and for the Indiana University Chemistry Department. The laboratory
performs and assists in magnetic resonance spectroscopy which
furthers the research goals of departmental faculty, staff, and
students. The following report summarizes the service and research
activities of the NMR Facility during 1995.
Summary of Facility Services
17 (45%) of 38 tenured or tenure-track faculty in the Chemistry
Department direct research programs which use the NMR Facility.
147 (59%) of approximately 250 graduate students, postdoctoral
fellows, and research associates in the Chemistry Department use
NMR Facility resources. Since some users are trained to use more
than one spectrometer, the sum of users trained on each spectrometer
is 177, 57 of whom were trained in 1995.
The NMR Facility is open 24 hours per day and 365 days per year
for collaborative or independent use by trained research chemists.
The "Average Usage by Hour" reported for each spectrometer
is based upon the total number of hours between January 1 and
November 30, 1995. However, each spectrometer was not available
for research during all hours, due to spectrometer maintenance,
usage by the NMR Facility Staff, etc. Thus, the "Average
Usage by Hour" is less than values based upon the number
of hours that the spectrometers were truly available for research.
Notable services provided in 1995 include:
- Training has been standardized
- Bulletins were developed to address important topics that
arise in routine NMR experiments.
- A series of workshops was conducted in the spring semester
to improve the training of spectrometer users.
Summary of Research Activities
Most NMR experiments performed by the NMR Facility Staff for researchers
are considered routine. These experiments are classified as a
"service", since the researcher is taught how to independently
perform the experiment (as mandated by NMR Facility policy). 12
non-routine research projects required collaboration beyond routine
service in 1995
Facility Developments
Spectrometer Improvements:
- The AM-500 spectrometer hardware was augmented to allow for
inverse-detect experiments.
- A 500 MHz Varian Inova 500 console and probes have been purchased
to replace the existing Bruker AM-500 console, datastations, sample
changer, and probes.
- A 400 MHz Varian Inova 400 console, magnet, and probes have
been purchased to replace the existing Nicolet NT-360 console,
magnet, and probes.
- A 300 MHz Varian Gemini 2000 console, datastations, and probes
have been purchased to replace the existing Varian XL-300 console.
Continuing Projects
- A computerized scheduling system is being developed.
- Computerized report generation from spectrometer accounting
records continues to be streamlined and improved for research
groups using all spectrometers and datastations.
- The development of non-routine 2D NMR experiments and spectrometer
automation will continue.
- Implementation of new spectrometer equipment is tentatively
scheduled as follows:
- Jan 29: Replacement of Bruker AM-500 console, sample-changer,
and probes with 500 MHz Varian Inova console and probes
- Jan 29: Replacement of Varian XL-300 console with 300 MHz
Varian Gemini 2000 console, workstation, and probes.
- Feb 5: Replacement of Nicolet NT-360 console, magnet, and
probes with 400MHz Varian Inova console, magnet, and probes
- Feb 10: Training of Inova-500 and Gem-300 users.
- Feb 15: Training of Inova-400 users.
