Spectroscopic TechniquesTo collect spectra with high sensitivity and resolution, we use a variety of cavity-enhanced spectroscopic techniques. |
 |
Chemical Physics of H3+H3+ is one of the most important ions in intersteallar chemistry. We study the nuclear spin dependence of the chemical physics of H3+, both its dissociative recombination rate and its reaction with H2. |
 |
High Resolution Mid-IR Spectroscopy With Quantum Cascade LasersWe aim to collect a rotationally-resolved, cold, gas-phase spectrum of the infrared allowed vibrational band of buckminsterfullerene at ~8.4 micron (1185 cm-1). |
 |
SCRIBESSCRIBES (Sensitive, Cooled, Resolved Ion BEam Spectroscopy) is a novel technique being developed in the McCall lab to acquire high-resolution vibrational spectra of astronomically important ions. |
 |
Solid HydrogenWe have performed measurements of the refractive index of solid para-hydrogen, and are using these measurements to develop a solid hydrogen Raman laser. |
 |
Supersonic Expansion Discharge SourceFor the SCRIBES project, a continuous source of rotationally cold ions is necessary. We are developing and characterizing an ion source that couples a DC discharge with a continuous supersonic expansion. |
