On the structural intricacies of a metabolic precursor: Direct spectroscopic detection of water-induced conformational reshaping of mevalonolactone
ddc:540
We use high-resolution rotational spectroscopy to investigate the structural intricacies of the lactone form of mevalonic acid, precursor of the mevalonate pathway. By combining microwave spectroscopy with supersonic expansions and quantum-chemical calculations, we determine the two most stable conformations of the precursor. [...]

Capturing the Elusive Water Trimer from the Stepwise Growth of Water on the Surface of the Polycyclic Aromatic Hydrocarbon Acenaphthene
ddc:530
Polycyclic aromatic hydrocarbons (PAHs) are key players in reaction chemistry. While it is postulated that they serve as a basis for ice grains, there has been no direct detection of PAHs in astronomical environments. [...]

Cold Snapshot of a Molecular Rotary Motor Captured by High-Resolution Rotational Spectroscopy
ddc:540
We present the first high-resolution rotational spectrum of an artificial molecular rotary motor. By combining chirped-pulse Fourier transform microwave spectroscopy and supersonic expansions, we captured the vibronic ground-state conformation of a second-generation motor based on chiral, overcrowded alkenes. [...]

Coherent Enantiomer-Selective Population Enrichment Using Tailored Microwave Fields
ddc:540
We report the experimental demonstration of coherent enantiomer-selective enrichment of chiral molecules by employing a novel microwave five-pulse scheme. Our results show that enantiomers can be selectively transferred to a rotational level of choice by applying sequences of resonant microwave pulses in a phase- and polarization-controlled manner.
