The Bowers research group specializes in nuclear magnetic resonance technique development, particularly in the area of signal enhancement. We employ NMR to obtain dynamical and structural information on technologically relavent materials, such as semiconductor nanostructures, nanotube systems, new types of polymers, and new energy storage materials. We employ density matrix/operator theory, statistical thermodynamics, and numerical simulations, and we also develop NMR instrumentation.
We are located in the New Physics Building on the corner of Gale Lemerand Drive and Museum Road on the University of Florida campus.

Nuclear magnetic resonance (NMR) is a versatile form of spectroscopy in which radiowaves are absorbed or emitted due to nuclear spin flips. NMR is used widely by chemists, physicists, biologists and engineers to obtain structural and dynamical information in molecules and materials of all sorts. However, the applicability of NMR is often limited by its inherently poor sensitivity. Because the energy of the radiofrequency quanta is typically much smaller than the thermal energy, kT, the orientation of the nuclear spins is almost completely random under most conditions. As a result, the resonant absorption and emission of radiowaves cancel, making it difficult to detect NMR. Our research focusses on methods for enhancing the NMR signal and/or increasing the detection sensitivity of NMR. Using the enhanced NMR methods which we help to develop, we study systems which would be difficult if not impossible to see by conventional NMR. We apply advanced NMR techniques to materials of technological importance, as enumerated below. On the theory side, we employ density matrix/operator calculations, statistical mechanics, and numerical simulations to help us discover and analyze new or anomalous phenomena.

There are always opportunities in our group for highly motivated graduate and undergraduate students, particularly in (but not necessarily limited to) the areas of physical, analytical and materials chemistry. We welcome undergraduate students interested in pursuing an honors thesis or who would just like to experience the excitement of advanced research! Our group meetings are held each Friday at 9:45am in the lab (B122, New Physics Building). Please contact us (russ@ufl.edu) for more information or to schedule a lab visit.

bruk2igor.exe is a win32 console application for batch conversion of Bruker Xwinnmr 1r binary spectrum files (SGI Irix, little endian to big endian conversion) to any one of three output formats : Igor Pro text files, DFP input files or 2-column text files. Here is the source code: bruk2igor.c. Please contact us about any problems or offer suggestions.
readme file for bruk2igor.exe. This program reads a list of bruker "1r" files to be converted. The list can be created using the unix "find command". For example,
find wag21d-rt -name "1r" > wag21d-rt/list.txt
ifid.exe is for bulk conversion of Bruker fids into ascii text files. Here is the source code: ifid.c. This program reads a list of bruker "fid" files to be converted. The list can be created using the unix "find command". For example,
find wag21d-rt -name "fid" > wag21d-rt/list.txt
would create a file named "list.txt" containing a list of "fid" files in the target directory, e.g. wag21d-rt. If necessary, the program converts from little endian to big endian format after reading the binary "fid" file suitable for intel x86 processors. The program reads the acqus files to obtain the dwell time. ifid.exe should be executed in the same folder as the list.txt file (without any command line argument), or alternatively, folder containing the "list.txt" can be specified as a command line argument.
mathnmrv2.0.nb is a Mathematica notebook file containing a collection of modules for NMR signal processing. The routines were specifically designed for interpolation, left shifting, phasing, and fourier transformation of Bruker fids. An example of data processing (deuterium quadrupole echo signals) is given here.
dfp2igor (source code: dfp2igor.c) is a utility program for converting the DFP output files into stacked spectra in Igor Pro text files. This program is useful If you are manually processing DFP output spectra with Igor Pro.
