Delayed extraction for improved resolution of ion/surface collision products by time-of-flight mass spectrometry
Autor: D. E. Riederer, Lisa L Haney
Publikováno v: Analytica Chimica Acta. 397:225-233
A time-of-flight mass spectrometer is described which contains a collision surface located behind the reflectron. This collision device uses delayed extraction (DE) to improve the instrument resolving power for ion/surface collision products formed b

Ejection of neutral molecules from ion-bombarded organic surfaces
Autor: R. Chatterjee, Zbigniew Postawa, D. E. Riederer, Nicholas Winograd
Publikováno v: Rapid Communications in Mass Spectrometry. 12:1226-1231
Time-of-flight distributions of neutral molecules ejected from various organic surfaces have been measured subsequent to 8 keV Ar+ and H2+ ion bombardment. The distributions show that depending on the physical and chemical nature of the substrate, th

Angular, energy, and population distributions of neutral atoms desorbed by keV ion beam bombardment of Ni{001}
Autor: D. E. Riederer, Chun He, Barbara J. Garrison, S. W. Rosencrance, Zbigniew Postawa, Nicholas Winograd, R. Chatterjee, C. Xu
Publikováno v: Scopus-Elsevier
Multi-photon resonance ionization, time-of-flight mass spectrometry and imaging techniques have been employed to measure the polar-angle, kinetic energy, and population distributions of Ni atoms desorbed from 5 keV Ar ion bombarded Ni{001}. The measu

Abstraction of multiple surface atoms by pyrazine, pyrene and HC2N ions on low-energy collisions with self-assembled monolayer surfaces
Autor: R. Graham Cooks, Matthew R. Linford, D. E. Riederer
Publikováno v: Journal of Mass Spectrometry. 30:241-246
Ion/surface reactions of pyrazine and pyrene molecular ions and the HC2N+· ion were investigated using an alkyl self-assembled monolayer surface consisting of hydrogenated and perdeuterated chains (CH3(CH2)15S–Au and CD3(CD2)15S–Au) intimately m

Energy disposal and target effects in hyperthermal collisions of ferrocene molecular ions at surfaces
Autor: H. W. Lee, R. G. Cooks, Heon Kang, D. E. Riederer, W. R. Cho, S. A. Miller
Publikováno v: The Journal of Physical Chemistry. 98:245-251
Ferrocene molecular ions undergo inelastic collisions at Si(100) and alkanethiol self-assembled monolayer surfaces (SAMs). Dissociation of the activated projectile follows its recoil from the surface; viz., surface-induced dissociation (SID) occurs b

Publikováno v: Organic Mass Spectrometry. 28:1021-1033
Collisions of C3F at self-assembled hydrocarbon, deuterated hydrocarbon and fluorocarbon surfaces yield fragment ions which are characteristics of both electronic excitation and vibrational excitation. Direct electronic excitation is indicated by los
