The impact of solvation on the structure and electric field strength in Li⁺GlyGly complexes

Abstract

To scrutinise the impact of electric fields on the structure and vibrations of biomolecules in the presence of water, we study the sequential solvation of lithium diglycine up to three water molecules with cryogenic infrared action spectroscopy.

Aspartame and Its Microhydrated Aggregates Revealed by Laser Spectroscopy: Water–Sweetener Interactions in the Gas Phase

“…In the last years, important progress in the study of the conformation of small biomolecules in microsolvation conditions has been achieved using cryogenic ion spectroscopy techniques (see examples − ). In those studies, the molecule of interest is monoprotonated or accompanied by a positively charged alkali metal, which enables trapping the species and further exploration using several spectroscopic techniques.…”
