CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishFive different hydrogen bonded conformers of the dimer of 2-propanol have been characterized by Fourier transform microwave spectroscopy. In all observed species the proton donor moiety adopts a gauche conformation. While in the gauche-monomer a transient chirality takes place, all dimers are classical chiral systems. The Ubbelohde effect has been observed upon OH  OD isotopic substitution and its structural effects – a 5 mÅ reduction of the O---O distance – quantitatively defined.

The Ubbelohde effect has been observed upon OH OD isotopic substitution and its structural effects – a 5 mÅ reduction of the O---O distance – quantitatively defined. |
