Sequential water molecule binding enthalpies for aqueous nanodrops containing a mono-, di- or trivalent ion and between 20 and 500 water molecules.
Sequential water molecule binding enthalpies, ΔHn,n-1, are important for a detailed understanding of competitive interactions between ions, water and solute molecules, and how these interactions affect physical properties of ion-containing nanodrops that are important in aerosol chemistry. Water molecule binding enthalpies have been measured for small clusters of many different ions, but these ...
متن کاملAverage sequential water molecule binding enthalpies of M(H2O)(19-124)2+ (M = Co, Fe, Mn, and Cu) measured with ultraviolet photodissociation at 193 and 248 nm.
The average sequential water molecule binding enthalpies to large water clusters (between 19 and 124 water molecules) containing divalent ions were obtained by measuring the average number of water molecules lost upon absorption of an UV photon (193 or 248 nm) and using a statistical model to account for the energy released into translations, rotations, and vibrations of the products. These val...
متن کاملNanometer patterning of water by tetraanionic ferrocyanide stabilized in aqueous nanodrops† †Electronic supplementary information (ESI) available: Complete citation for ref. 6, 43, 52 and 54, expanded region of nESI spectra in Fig. 1, comparison of individual radial distribution functions and atomic coordinates for the lowest energy Fe(CN)6 4–(H2O)160 structure along the molecular dynamics trajectory illustrated in Fig. 7.

Formation of the small, highly charged tetraanion ferrocyanide, Fe(CN)6 4 , stabilized in aqueous nanodrops is reported. Ion–water interactions inside these nanodrops are probed using blackbody infrared radiative dissociation, infrared photodissociation (IRPD) spectroscopy, and molecular modeling in order to determine how water molecules stabilize this highly charged anion and the extent to whi...

The interaction of hGH with some metal ions ( ) at 27°C in NaC1 solution, 50 mM was studied using Isothermal titration calorimetry. There is a set of three identical and non-interacting binding sites for binding of all these metal ions, expect . The intrinsic association equilibrium constants () are not very different for and , and also their molar enthalpies of binding (KJ/mol for and KJ/mo...
متن کاملStructural and electrostatic effects at the surfaces of size- and charge-selected aqueous nanodrops† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c7sc00481h Click here for additional data file.
The effects of ion charge, polarity and size on the surface morphology of size-selected aqueous nanodrops containing a single ion and up to 550 water molecules are investigated with infrared photodissociation (IRPD) spectroscopy and theory. IRPD spectra of M(H2O)n where M 1⁄4 La, Ca, Na, Li, I , SO4 and supporting molecular dynamics simulations indicate that strong interactions between multiply...
