Raman Spectroscopy Under Liquid Nitrogen (RUN) / Springer Series on Atomic, Optical, and Plasma Physics Bd.121 (PDF)

publications in journals including Science and The Journal of the American Chemical Society. Important accomplishments include describing blinking suppression in quantum dot nanostructures, probing the chiroptical response of single molecules, and unraveling the origins of spectroscopic defects in organic light emitting diode (OLED) devices. Dr. Hammer joined the University of Mississippi Department of Chemistry and Biochemistry in 2007. He received a Faculty Early Career Development (CAREER) Award from the National Science Foundation (NSF) in 2010 to spectroscopically track the evolution of noncovalent interactions from the single molecule level to the condensed phases. As part of this grant he developed the department's award-winning summer research program for undergraduates. Professor Hammer was named the Margaret McLean Coulter Professor of Chemistry and Biochemistry in 2020. He received the College of Liberal Arts Award for Research, Scholarship and Creative Achievement for Senior Faculty in 2018 and the Faculty Achievement Award in 2021.


Ethan C. Lambert was born in Corinth, Mississippi and graduated from Kossuth High School in May 2019. He enrolled at the University of Mississippi in Fall of 2019 and is currently pursuing a B.S. in Chemistry degree. He enjoys studying physical and chemical processes at the fundamental level and began research under Dr. Nathan Hammer at the beginning of his sophomore year. Ethan has used Raman spectroscopy and quantum computational chemistry to study several chemical systems, including charge transfer events, vibrational structure and symmetry, and enhancing Raman spectral signal. Ethan's current projects focus on the study of inter- and intramolecular photoinduced charge transfer events in artificial photosynthetic systems via ultrafast transient absorption spectroscopy and anisotropy. Ethan is set to graduate with an Honors B.S. in Chemistry in May 2023.
J. Stewart Hager received his Ph.D. from the University of Tennessee in Molecular Physics. He studied high-resolution infrared spectroscopy, molecular vibrational-rotational theory, atmospheric remote sensing. He worked with Dr. Compton as a research associate, where he helped develop the RUN technique. He served as a Senior Research Associate at Atmospheric and Environmental Research (AER) in Lexington, MA from 2005-2008, where he was a team member of NASA's Active Sensing of CO2 Emissions over Nights, Days, and Season (ASCENDS) satellite. He determined sensitivities of DIAL measurements for CO2 due to atmospheric conditions for ASCENDS. He started the company Hager Environmental and Atmospheric Technologies, where he developed a vehicle exhaust remote sensing device called Emissions Detection And Reporting (EDAR). EDAR has been deployed in many countries, including Great Britain, Belgium, Germany, France, and Italy, and has received over 40 patents worldwide.
