A study was conducted relating to research on the vibrational spectrum of ethanol monomers and the issue of the rotational isomerism of ethanol was conducted. The experiment aimed to demonstrate that the comparison between spectra calculated according to the DFT method for both conformers and the observed ones enable researchers to conclude that either one or the other species can be stabilized according to the nature of the matrix. Results of the study are discussed.

The simultaneous existence of valence and dipole-bound states of the uracil anion was investigated in a cross beam experiment. Specifically, Rydberg electron attachment to gas-phase isolated uracil molecules and mixed uracil-argon clusters was analyzed. Field-detachment measurements showed that attachment and evaporation of a single argon atom is enough to switch from dipole-bound to valence monomer uracil anions. The results were consistent with two previous theoretical predictions.
