A series of high resolution spectroscopic studies of small chiral molecular adducts and low resolution infrared multiphoton dissociation studies of protonated serine clusters will be presented. Using the experimentally spectral signatures, complemented with the ab initio calculations, we examine the chiral discriminating forces at play in these molecular systems. I will also discuss our two-pronged approach to study the effects of solvent- solute hydrogen-bonding on chiroptical measurements using both high resolution spectroscopy and vibrational circular dichroism (VCD) spectroscopy. We observed that some vibrational bands of an achiral molecule, such as water, can show significant VCD strength through hydrogen-bonding to a chiral molecule. This effect, termed chirality transfer, will be discussed.
