The HS3 radical and the HS3− anion, the sulfur analogues of HO3 and HO3−, have been detected for the first time by mass spectrometric experiments performed in the gas phase. The structural and energetic features of HS3 and HS3− have been investigated by ab initio calculations.

Abstract
The HS3 radical and the HS3− anion, the sulfur analogues of HO3 and HO3−, have been detected for the first time by mass spectrometric experiments performed in the gas phase. The structural and energetic features of HS3 and HS3− have been investigated by ab initio calculations. Both HS3 and HS3− are characterized by HSSS open-chain structures, stable toward the dissociation into S2 and HS0/−. HS3 adds to HS and HS2 as the known HSn species, and HS3− is the conjugate base of a strong Brønsted acid, the trisulfane HSSSH.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
