Abstract
Complex and poorly resolved Cu2+ and VO2+ doped single-crystal
electron paramagnetic resonance (EPR) spectra are some of the
serious problems that exist in this area. In order to help the resolution of this
sort of spectra, and for easily resolvable spectra as well, a versatile computer
program known as EPR RESolution, or EPRES, is presented. All detectable
line positions in the single-crystal spectra taken in three mutually perpendicular
planes are given as input. The program plots these line positions. The
user then manually determines the lines by selecting the true data points on
the plot and fitting them to a well-known variation function. If selection is
not suitable, the process is canceled and renewed. By this process, as many
resolvable lines as in the spectra can be resolved and determined. The user
then groups the resolved lines according to the paramagnetic center to
which they belong. This includes the attribution of correct nuclear spin I
and MI to correct lines. After this step, hyperfine and g tensor elements
can be found, constructed, and diagonalized.
