High resolution spectrum of methyl lactate, a chiral alpha-hydroxyester, has been investigated using a molecular jet Fourier transform microwave spectrometer. High level ab initio calculations were employed to study the conformational isomerism of methyl lactate. The observed rotational spectrum confirms

Chiral recognition and subsequent selective self-organisation into hydrogen-bonded n-mers is observed in supersonic methyl lactate expansions. The nu(OH) and nu(C=O)-vibrations are investigated by ragout-jet FTIR-spectroscopy and lead to the assignment of homo- and heterochiral clusters of at least three different

Determining absolute configuration of chiral molecule can be achieved by using vibrational optical activity (VOA) measurement methods, such as vibrational circular dichroism and Raman optical activity (ROA). Recently, vibrationally resonant sum frequency generation and difference frequency generation utilizing circularly polarized
