At the GRU Lab at Tennessee Tech University, we explore the molecular world using custom-built instruments related to high-resolution spectroscopy to tackle questions in physical chemistry, astrochemistry, and beyond. Our core expertise lies in Fourier Transform Microwave (FTMW) spectroscopy, a powerful technique for probing the rotational structure of molecules and revealing insights into their geometry, internal motions, and quantum behavior.
We designed and constructed Tennessee’s first FTMW spectrometer, and continue to innovate by developing new tools to study weakly bound van der Waals complexes, photochemically reactive species, and tunneling phenomena in molecules. Our work bridges fundamental science and real-world applications, from investigating the chemistry of interstellar space to collaborating with the local wine industry on quality control methods.
Students in our lab gain hands-on experience in:
- Building scientific instruments and high-vacuum systems
- Applying various molecular spectroscopic methods to interrogate fundamental molecular properties such as geometry, conformational preferences, quantum tunneling, nuclear and electron spin interactions, dipole moments, intermolecular forces, and structural planarity
- Setting up spectroscopic experiments, data acquisition, spectral fitting, and interpretation
- Using computational quantum chemical calculations to support spectral predictions and data analysis
- Implementing high-energy laser and photolysis techniques to study reaction dynamics
- Engaging in CAD design, 3D modeling, and additive manufacturing
- Programming in Python and LabVIEW for instrument control and data processing
Our group includes graduate and undergraduate researchers from chemistry, physics, and engineering. We welcome curious minds and offer flexible opportunities for students to join ongoing projects, co-author publications, and present at national conferences.
