The many binding sites of hydantoin Physical chemistry, chemical physics 20(8), 5545 - 5552 (2018) [10.1039/C7CP06518C]   Prebiotic hydantoin and its complexes with one and two water molecules are investigated using high-resolution broadband rotational spectroscopy in the 2–8 GHz frequency range. The hyperfine structure due to the nuclear quadrupole coupling of the two $^{14}$N atoms is analysed for the monomer and the complexes.

We observed and analysed the rotational spectra of the ground state of the molecule and ten vibrationally excited states with energies between 180–500 cm$^{−1}$.

On the structural intricacies of a metabolic precursor: Direct spectroscopic detection of water-induced conformational reshaping of mevalonolactone The journal of chemical physics 147(12), 124310 - (2017) [10.1063/1.4997162]   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.

While it is postulated that they serve as a basis for ice grains, there has been no direct detection of PAHs in astronomical environments. [...] Published on 2017-11-07.

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.

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.
