Job Duties:

This researcher will learn how to operate and interpret data taken on the electron paramagnetic resonance (EPR) and transient-electron paramagnetic resonance spectrometer (tr-EPR) at the National Renewable Energy Laboratory for the RENEW grant and the NSF-CCI grant.

Position Summary:

This researcher will work primarily with Dr. Lazorski on a research project studying a series of Lewis Acid appended Mn(IV)oxo complexes and their light absorption properties using electron paramagnetic resonance (EPR) and/or transient-electron paramagnetic resonance spectrometer (tr-EPR). This researcher will work with Dr. Mulder at National Renewable Energy Laboratory to obtain and/or analyze data on our complexes and may also work with Drs. Gish, Braunecker, Mulder, and Reid. Additionally, this student will be able to use the instrumentation and knowledge they gain through training with Drs. Lazorski and Mulder to help advance the objectives of the NSF-CCI grant work.

Pay Rate: $25.7/hr

Temporary Employee is allowed to work:

· 12 months @ 36 hr/week up to a max of 1858 hours

Pay Sources:

1. 57.8% of Salary from GR_0000407 DOE – RENEW – Designing First Row Transition Metal Photosensitizers

2. 42.2% of Salary from GR_0000390 CSU-NSF – Center for Sustainable Photoredox Catalysis (SuPRCat) 9/1/23-8/31/2

In addition to the EPR and tr-EPR methods, the researcher may also use the following characterization methods to gain the following information about Lewis Acid appended Mn(IV)oxo and other relevant complexes:

Dark dielectric loss spectroscopy – provides information about the dipole moment and polarizability of the complex in the ground state
Nanosecond transient absorption spectroscopy – provides information about the energy of the excited states when photoexcited and how long those excited states live
Spectroelectrochemistry – provides information about the energy of the excited states when oxidized or reduced. This technique allows us to model the response in the transient absorption spectroscopy.
UV-vis spectroscopy – provides information about the energy of the ground state.
Fluorescence spectroscopy – provides information about the energy of excited states that emit light Electrochemistry – provides information about the oxidation states of the compound, and therefore, the energy of the ground state species in different oxidation states.
