Abstract
Krypton reacts with cationic ozone derivatives in the gas phase under Fourier-transform ion cyclotron resonance conditions to yield stableKrOn+ (n = 1,2) and KrOH+ ions. The stability properties of these species are contrasted with previous experimental data and with theoretical predictions. The persistency of gaseous KrO+ and KrOH+ ions at low pressures (4 × 10−8 Torr) and room temperature is justified by their pronounced krypton-oxygen bond dissociation enthalpy estimated to be as large as 56.8 and 40.5 kcal mol−1, respectively, on the grounds of ab initio density functional calculations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
