Postdoctoral Appointee - Molecular Spectroscopy
Job posting number: #7068509 (Ref:672734)
Posted: August 4, 2020
Job Description**Are you passionate about research and want to utilize state-of-the-art scientific facilities? Do you enjoy collaborating with dynamic, multidisciplinary research teams?** We seek one to two motivated postdoctoral appointees to assist us in research exploring the fundamental spectroscopy of free radicals and reactive intermediates. The successful candidate will access a wide array of state-of-the-art custom physical chemistry apparatuses, including Fourier transform visible and infrared spectrometers, a chirped-pulse microwave / time-of-flight mass spectrometry apparatus, time-resolved grating spectrometers with image-intensified cameras, and infrared optical parametric oscillators for infrared-visible double resonance measurements. You will access supersonic jet expansion sources, hyperthermal radical production sources, and photolysis cell environments, including high pressure / high temperature cells. Using these powerful tools you will explore, at a fundamental level, all aspects of free radical spectroscopy, including structural characterization and the effect of pressure and temperature on quantitative absorption cross sections. Experimental results will be compared to state-of-the-art theoretical predictions that are currently underway. On any given day, you may: + Collaborate with researchers on customization of microwave, infrared, and visible spectroscopy apparatuses. + Acquire spectra with quantitative wavenumber and intensity measurements. + Analyze spectra including spectroscopic fitting and collaboration with theoretical spectroscopy colleagues. + Grasp the larger goals of the project, proposing innovative solutions and new directions. You will partner with a multi-investigator team, present results at national/international meetings, and publish research in high profile peer-reviewed journals.
+ PhD degree in physics, chemistry, or a closely related field + Significant experience in microwave, infrared, or optical spectroscopy in the gas phase. + Strong record of publications in peer-reviewed journals
+ Experience with double resonance optical spectroscopy + Experience with Fourier transform spectroscopy + Experience with time-of-flight mass spectrometry + Experience with electronic structure calculations and predictions of absorption spectra using Multi-configurational Time-Dependent Hartree methods. + Ability to address complex problems creatively, and to work effectively both independently and in collaboration with other researchers. + Experience with LabVIEW, MATLAB, Pgopher software environments
The Combustion Chemistry and Diagnostics Department is part of Sandia's Combustion Research Facility (CRF) in Livermore, California, where over 100 scientists, engineers, and technologists conduct basic and applied research to improve our nation's ability to use and control combustion processes efficiently and cleanly. Under the principal sponsorship of the Department of Energy's Office of Basic Energy Sciences, the Combustion Chemistry and Diagnostics Department conducts fundamental experimental, theoretical, and modeling research to develop a foundational understanding of the key chemical processes that underlie the complex mechanisms of combustion. Additional programs investigate the effects of combustion emissions on atmospheric composition and climate. Research areas include chemical dynamics and spectroscopy, theoretical and experimental chemical kinetics, flame chemistry and modeling, and gas-phase and particulate diagnostics development and deployment.

This position does not currently require a Department of Energy (DOE) security clearance. Sandia will conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Furthermore, employees in New Mexico need to pass a U.S. Air Force background screen for access to Kirtland Air Force Base. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause access to be denied or terminated, resulting in the inability to perform the duties assigned and subsequent termination of employment. If hired without a clearance and it subsequently becomes necessary to obtain and maintain one for the position, or you bid on positions that require a clearance, a pre-processing background review may be conducted prior to a required federal background investigation. Applicants for a DOE security clearance need to be U.S. citizens. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted. Members of the workforce (MOWs) hired at Sandia who require uncleared access for greater than 179 days during their employment, are required to go through the Uncleared Personal Identity Verification (UPIV) process. Access includes physical and/or cyber (logical) access, as well as remote access to any NNSA information technology (IT) systems. UPIV requirements are not applicable to individuals who require a DOE personnel security clearance for the performance of their SNL employment or to foreign nationals. The UPIV process will include the completion of a USAccess Enrollment, SF-85 (Questionnaire for Non-Sensitive Positions) and OF-306 (Declaration of for Federal Employment). An unfavorable UPIV determination will result in immediate retrieval of the SNL issued badge, removal of cyber (logical) access and/or removal from SNL subcontract. All MOWs may appeal the unfavorable UPIV determination to DOE/NNSA immediately. If the appeal is unsuccessful, the MOW may try to go through the UPIV process one year after the decision date.
All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law. : This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.
