Postdoctoral Position in Visible and Infrared Spectroscopy
A postdoctoral position will be available starting February 1, 2008 in the
laboratory of Prof. T.C. Steimle at Arizona State University. The
scientific objective is the experimental determination of the fundamental
properties that elucidate the electronic, and hence chemical, character of
small, transient, metal containing molecules. The molecules are venues for
understanding bonding in more complex systems, useful as probes of
magnetic and electric fields in remote energetic environments, and are
targets for Stark deceleration and/or magnetostatic trapping due to their
enormous response to applied fields. Particular emphasis will be placed
on determination of the permanent electric dipole moment, ƒÝel, magnetic
dipole moment, ƒÝm and magnetic hyperfine interactions. Two classes of gas-
phase spectroscopic studies on metal containing radicals will be
implemented: a) visible and near infrared electronic spectroscopy using
laser induced fluorescence detection, b) mid-infrared vibrational
spectroscopy in the fundamental stretching region for OH, CH and NH
groups. Unprecedented spectral resolution is realized by the combination
of skimmed molecular beams with monochromatic radiation generated either
with commercial visible lasers or a non-commercial difference frequency
laser system. The information obtained from these ultra-high resolution
spectroscopic studies includes geometric structure, the nature of the
chemically relevant valence electrons (via hyperfine structure), charge
distribution from ƒÝe, and assignment of spin and orbital angular momenta
from ƒÝm. The measurement of ƒÝe and ƒÝm for transition metal containing
radials is nearly unique to our laboratory.
A potential postdoctoral fellow should be highly motivated and have
experience with tunable laser systems. The individual should have a
penchant for experimental studies involving high-tech laser and molecular
beam instrumentation and versed in the application of molecular quantum
mechanics. This is an excellent opportunity for a motivated individual to
advance his or her career in a well-funded, highly productive research
environment.
Interested individuals should send an electronic or hard copy resume
including at least two references to: Prof. T.C. Steimle, Department of
Chemistry and Biochemistry, Arizona State University, Tempe, USA
