Mass Spectra and Photodetachment of Sodium Fluoride Negative Ion Clusters
نویسنده
چکیده
A flowing afterglow discharge ion source with NaF vaporized into the flow produces the expected stable anions F-(NaF),, as well as the unusual species Na(NaF); and (NaF); (n < 17). The dominance of (NaF); suggests that it has a particularly stable structure. A fixed-frequency laser has been used to photodetach electrons from mass-selected ion beams extracted from the flowing afterglow. Photoelectron energy spectra, vertical detachment energies and estimates of adiabatic electron affinities are reported for the (NaF); and Na(NaF); ions. The F(NaF); ions are found to be too stable for photodetachment at 488 nm.

POSITIVE AND NEGATIVE ION MASS SPECTRA OF RING - SUBSTITUTED NITROBENZENES
The 70 ev positive and negative ion mass spectra of ring-substituted nitrobenzenes were studied. The influence of the substituent group on the fragmentation modes of the molecular ions is discussed. The effect of pressure in the formation of negative ions was also studied. As expected, the ratio of fragment ions to negative molecular ions decreased with increasing pressure in ion source.
متن کاملAluminum Zintl anion moieties within sodium aluminum clusters.
Through a synergetic combination of anion photoelectron spectroscopy and density functional theory based calculations, we have established that aluminum moieties within selected sodium-aluminum clusters are Zintl anions. Sodium-aluminum cluster anions, Na(m)Al(n)(-), were generated in a pulsed arc discharge source. After mass selection, their photoelectron spectra were measured by a magnetic bo...
