Chemical bonding - Atomic Structure, Intermolecular Forces, Covalent Bonds: To understand bond formation, it is necessary to know the general features of the electronic structure of atoms—that is, the arrangement of electrons around the central nucleus.
Re: Atomic Weight from 2 Sources «Reply #1 on:May 04, 2014, 03:43:35 AM » For me NIST is a definite source: http://www.nist.gov/pml/data/comp.cfm So Co is 58.9331950(7). Number in parentheses means uncertainty of the given number: ...

export CRITIC_HOME=/home/alberto/programs/critic2dir This variable is necessary for critic2 to find the atomic densities, the cif dictionary, and other data. These data should be in${CRITIC_HOME}/dat/. Lastly, a number ofexternal librariescan be used to extend critic2's capabilities, includ...
Chemisorption of 2-Mercaptoethanol on Silver, Copper, and Gold: Direct Raman Evidence of Acid-Induced Changes in Adsorption/Desorption Equilibria Molecules of 2-mercaptoethanol (ME) were spontaneously chemisorbed on silver, copper, and gold surfaces. Surface-enhanced Raman scattering investigation re....
Using first-principles all-electron band structure method, we have systematically calculated the natural band offsetsΔEvbetween all II–VI and separately between III–V semiconductor compounds. Fundamental regularities are uncovered: for common-cation systemsΔEvdecreases when the cation atomic number inc...
Here we determine the 3D atomic positions of M/HEA nanoparticles using atomic electron tomography36 and quantitatively characterize the local lattice distortion, strain tensor, twin boundaries, dislocation cores and chemical short-range order (CSRO). We find that the high-entropy alloys have larger ...
