Sodium doping and reactivity in pure and mixed ice nanoparticles

Popis výsledku v původním jazyce

Doping of clusters by sodium atoms and subsequent photoionization (NaPI) is used as a fragmentation-free cluster ionization method. Here we investigate different clusters using NaPI and electron ionization (EI) with a reflectron time-of-flight mass spectrometer (RTOF). The mass spectra of the same clusters ionized by NaPI and EI reveal significant differences which point to Na reactivity in the clusters. First, we discuss mixed XM(H2O)N (X = HNO3, N2O) clusters where reactions between Na and molecules Xleads to the ?cluster invisibility for the NaPI method. Second, mixed (NH3)M(H2O)N clusters are observed by both methods, but they reveal different cluster compositions, and the mass spectra suggest that neither the EI nor the NaPI spectrum correspondsexactly to the neutral cluster distribution. Finally, we discuss the reactions of Na in pure water clusters as a function of the number of Na atoms doped into the clusters. In summary, we present experimental evidence that the NaPI method
