Our research program focuses on applying and developing new spectroscopic tools to determine chirality and to establish chirality recognition/induction/amplification mechanisms at the molecular level. Our recent rotational spectroscopic studies of clusters of fluoroethanols highlight the importance of bifurcated H-bonds and F···F attractive interactions and their decisive roles in conformational preference. We also apply vibrational circular dichroism and Raman optical activity to probe how chiral molecules interact with each other and with solvent molecules directly in solution, leading to the clusters-in-a-liquid solvation model. The interplay between experiment and theory is essential for all the work described. Finally, a recently developed hybrid laser-mass spectrometry will also be described.
