ABSTRACT
In this award, funded by the Chemical Measurement and Imaging Program of the Division of Chemistry, Professor Gordon Brown of Coker College and his undergraduate student researchers will be supported to study the intermolecular bonding in: (1) van der Waals complexes between carbon dioxide and nitrogen heterocycles and (2) complexes between halogen-containing small molecules and Lewis bases. The researchers will study these species with chirped-pulse Fourier transform microwave spectroscopy.
Microwave spectroscopy is an important physical chemical method that gives precise information about molecular geometry and binding. The classes of species that Professor Brown and his students will study will provide information on potential carbon-capture/storage materials as well as fundamental information about the intermolecular interactions between halogen-containing species. The undergraduate students working on this project will gain useful experience in conducting physical chemical research with state-of-the-art equipment, and will be well-prepared for further study in the chemical sciences.

PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
In this project, microwave spectroscopy was used to study interactions between carbon dioxide and a variety of chemicals. This research will guide the design of the next generation of materials used for carbon capture and storage (CCS). Microwave spectroscopy is capable of measuring very precise geometries (bond lengths and bond angles) of molecules as well as measuring the forces that hold them together. This information can be valuable in understanding interactions between carbon dioxide and the active sites in CCS materials. This project was successful in measuring and analyzing the interactions of carbon dioxide with a series of related nitrogen-containing organic compounds.
A second outcome of this project was the design and construction of a low-cost, low-frequency microwave spectrometer. The design modified the state-of-the-art low-frequency spectrometer in the field to make it much less expensive, thus making it suitable for use at a small, primarily-undergraduate institution.
The third outcome of this project was the training of undergraduate students in the field of microwave spectroscopy, and more generally, in the field of scientific exploration. The students at our institution were trained to perform experiments, construct and troubleshoot complex instrumentation, analyze data, and present results and analysis of experiments at regional, national, and international conferences. Students involved in this project have gone on to attend universities in pursuit of advanced degrees. Other students have obtained jobs working in chemistry laboratories for private companies.
