POSTDOCTORAL POSITION
MULTIRESONANT SPECTROSCOPY AND DYNAMICS OF REACTIVE INTERMEDIATES
I am looking for a postdoc to join with us in our work on the electronic
spectroscopy of free-radicals. In this program, we use multiple steps of
resonant excitation to lift photolytically produced radicals to selected
single rovibronic states near and above first ionization thresholds.
Positions and lineshapes of spectral features convey information on
state-to-state relaxation dynamics in these highly excited molecules.
Results are interpreted within the electron-cation scattering framework of
Multichannel Quantum Defect Theory. Systems of interest include formyl,
vinoxy, acetyl, carbamoyl (NH2CO), HOCO, and some other small free
radicals. Project work will develop new ways to state-selectively excite
these molecules, determine their thermochemistry with respect to
rotationally resolved ionization limits, explore mode selectivity in
electron-cation inelastic scattering, and characterize the higher
vibrational-rotational structure of corresponding cations. Equipment
available includes molecular-beam quadrupole and time-of-flight mass
spectrometers, as well as a ZEKE high-resolution pulsed-field threshold
ionization apparatus. Spectroscopic light is provided by excimer and
Nd:YAG pumped dye lasers together with high-resolution and broad-band
optical parametric oscillators. For recent papers, see:

Those interested should send a CV and arrange for three letters of
recommendation to reach me electronically or by mail to the address below.
