A Critical Look at Linus Pauling’s Influence on the Understanding of Chemical Bonding

open access: yesMolecules, 2021
The influence of Linus Pauling on the understanding of chemical bonding is critically examined. Pauling deserves credit for presenting a connection between the quantum theoretical description of chemical bonding and Gilbert Lewis’s classical bonding ...

A química orgânica na consolidação dos conceitos de átomo e molécula Organic chemistry in the consolidation of the concepts of atom and molecule

open access: yesQuímica Nova, 2009
The present work discusses the appearance of the concepts of valence and molecular structure, and describes the appropriation and evolution of the concept of molecule in the period following the publication of Avogadro's Hypothesis.

Geometric and electronic structure probed along the isomerisation coordinate of a photoactive yellow protein chromophore

open access: yesNature Communications, 2020
Resolving concerted nuclear and electronic motion in real-time is a primary goal in chemistry. The authors monitor nuclear and valence electronic dynamics in the excited state single-bond isomerisation of a chromophore of photoactive yellow protein ...

Chemical Bonding: The Journey from Miniature Hooks to Density Functional Theory

open access: yesMolecules, 2020
Our modern understanding of chemistry is predicated upon bonding interactions between atoms and ions resulting in the assembly of all of the forms of matter that we encounter in our daily life. It was not always so.

Analysis of Students’ Chemical Bonding Misconception with A Four-Tier Diagnostic Test

open access: yesJTK (Jurnal Tadris Kimiya), 2022
Students had difficulty understanding the chemical bonding concept because of its complex and abstract nature. This difficulty could lead to chemical bonding misconceptions.

Iron-based trinuclear metal-organic nanostructures on a surface with local charge accumulation

open access: yesNature Communications, 2018
Polynuclear metal-organic coordination complexes are often inaccessible by traditional synthetic chemistry methods. Here, the authors use on-surface supramolecular chemistry to form a planar trinuclear Fe complex, in which an accumulation of electrons ...

Metal–Metal Bond in the Light of Pauling’s Rules

open access: yesMolecules, 2021
About 70 years ago, in the framework of his theory of chemical bonding, Pauling proposed an empirical correlation between the bond valences (or effective bond orders (BOs)) and the bond lengths.

Styrofoam-and-Velcro: An Alternative to Ball-and-Stick Models

open access: yesJournal of Microbiology & Biology Education, 2014
For students learning biology at introductory levels, one of the most significant instructional barriers is their lack of preparation in chemistry. In upper-division college chemistry and biology courses, students employ ball-and-stick models in order to

Redox Potential and Crystal Chemistry of Hexanuclear Cluster Compounds

open access: yesMolecules, 2021
Most of TM6-cluster compounds (TM = transition metal) are soluble in polar solvents, in which the cluster units commonly remain intact, preserving the same atomic arrangement as in solids.

Accurate thermochemistry at affordable cost by means of an improved version of the JunChS‐F12 model chemistry

open access: yesJournal of Computational Chemistry, 2023
The junChS‐F12 composite method has been improved by means of the latest implementation of the CCSD(F12*)(T+) ansatz and validated for the thermochemistry of molecules containing atoms of the first three rows of the periodic table.
