Polarized spectroscopy of Sm3+ ions in monoclinic KGd(WO4)2 crystals [PDF]
EPJ Web of Conferences, 2023 We report on a polarization-resolved spectroscopic study of Sm3+-doped monoclinic KGd(WO4)2 crystals. The transition probabilities for Sm3+ ions were calculated using a modified Judd-Ofelt theory.

Ion/ion chemistry of high-mass multiply charged ions [PDF]
Mass Spectrometry Reviews, 1998 Electrospray ionization has enabled the establishment of a new area of ion chemistry research based on the study of the reactions of high-mass multiply charged ions with ions of opposite polarity. The multiple-charging phenomenon associated with electrospray makes possible the generation of multiply charged reactant ions that yield charged products as ...

Distribution of Oil, Water, and Ions Near the Neutral Calcite Surface in the Presence of Low and High Salinity Water: Molecular Dynamics Simulation [PDF]
Journal of Petroleum Science and Technology, 2023 Low salinity water flooding has a significant impact on the recovery of carbonate reservoirs. In this paper, the molecular dynamics simulation was carried out to investigate the distribution of ions (Na+, Cl-, Ca2+, Mg2+, and SO42-), water, and oil ...

An ion trap-ion mobility-time of flight mass spectrometer with three ion sources for ion/ion reactions [PDF]
Journal of the American Society for Mass Spectrometry, 2009 This instrument combines the capabilities of ion/ion reactions with ion mobility (IM) and time-of-flight (TOF) measurements for conformation studies and top-down analysis of large biomolecules. Ubiquitin ions from either of two electrospray ionization (ESI) sources are stored in a three dimensional (3D) ion trap (IT) and reacted with negative ions from

Hydrated Ions: From Individual Ions to Ion Pairs to Ion Clusters
The Journal of Physical Chemistry B, 2015 The structure of hydrated ions plays a central role in chemical and biological sciences. In the present paper, five ions, namely, Na(+), K(+), Mg(2+), Ca(2+) and Cl(-), are examined using molecular dynamics simulations. In addition to hydrated individual ions and ion pairs identified previously, hydrated ion clusters containing 3, 4, 5, or more ions ...

Journal of the American Society for Mass Spectrometry, 2006 By Yates, Bouma, and Radom's definition, distonic radical ions are those formally arising by ionization of diradicals or zwitterionic molecules (including ylides). These ions differ, therefore, from conventional radical ions by displaying the charge site and unpaired electron site (spin) localized mandatorily on separate atoms or group of atoms; that ...
