Far-infrared Spectroscopy of Biomolecules (Archived)

Completed

We employ novel complimentary measurement and theoretical techniques to explore the low frequency intramolecular dynamics of model biological molecules including amino acids, short peptides with constrained structures, proteins with well-defined tertiary structures and DNAs. Our current efforts

Platform for Realizing Integrated Molecule Experiments (PRIME)

Ongoing

Blackbodies realize a clear relationship between radiated power and temperature through Planck’s law. While a reliable instrument for temperature and power calibrations, blackbodies are afflicted with a plethora of systematics (e.g., non-ideal emissivity, propagation loss, temperature gradients

Precision Spectroscopy and Quantum Control of Trapped Molecular Ions

Ongoing

Spectroscopy and Quantum Control of Molecular Ions Molecules exhibit vibration and rotation of their nuclei, degrees of freedom not present in atoms, and less stringent selection rules for transitions. This creates experimental challenges and great opportunities for exploring new physics. In this
