Development of a sensitive mid-infrared spectrometer for the study of cooled molecular ions
… optical heterodyne molecular spectroscopy (NICE-OHMS) system has been developed and characterized through rovibrational spectroscopy of methane. In addition, an attempt was made to use this spectrometer to probe molecular ions focused into an ion beam. Challenges inherent to laboratory …

Spectroscopic investigations of the X and A state dynamics of ¹³C₂H₂
… Optical Heterodyne Molecular Spectroscopy (NICE-OHMS) and Stimulated Emission Pumping (SEP) are employed to study the spectroscopy and dynamics of acetylene. All of these experiments focus on 13C2H2 instead of 12C2H2, except for the Cavity Ring-Down measurements. These experiments …

The NICE-OHVMS technique: realizing the full potential of precision molecular ion spectroscopy
… Heterodyne Velocity Modulation Spectroscopy (NICE-OHVMS) is one of the most sensitive spectroscopic techniques specific to molecular ions. NICE-OHVMS relies on the combination of three separate techniques, each of which is a powerful tool. Cavity enhancement extends the interaction pathlength …
