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.
EnglishThe effect of pressure on circular dichroism (CD) spectra of the octahedral chiral Λ- and Δ-tris-[cyclic O,O′,1(R), 2(R)-dimethylethylene dithiophosphato]chromium(III) complexes, Λ- and Δ-Cr[(R,R)bdtp]3, in the solid state has been studied. The pressure range investigated was 0-4 GPa. A method for measuring CD spectra under pressure is described. Results on polycrystalline samples in nujol indicate that the configuration at the metal centre of the chiral chromium complex inverts from the Δ- to the Λ-form, which eventually is the most stable at high pressure.
