3. Computational chemistry - Wikipedia

   en.wikipedia.org/wiki/Computational_chemistry

   Computational chemistry is a branch of chemistry that uses computer simulations to assist in solving chemical problems. [ 2 ] It uses methods of theoretical chemistry incorporated into computer programs to calculate the structures and properties of molecules, groups of molecules, and solids. [ 3 ]

4. Retrosynthetic analysis - Wikipedia

   en.wikipedia.org/wiki/Retrosynthetic_analysis

   Retrosynthetic analysis. Appearance. Retrosynthetic analysis is a technique for solving problems in the planning of organic syntheses. This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents. Each precursor material is examined using the same method.

5. Stiff equation - Wikipedia

   en.wikipedia.org/wiki/Stiff_equation

   Stiff equation. In mathematics, a stiff equation is a differential equation for which certain numerical methods for solving the equation are numerically unstable, unless the step size is taken to be extremely small. It has proven difficult to formulate a precise definition of stiffness, but the main idea is that the equation includes some terms ...

6. Stoichiometry - Wikipedia

   Stoichiometry. A stoichiometric diagram of the combustion reaction of methane. Stoichiometry (/ ˌstɔɪkiˈɒmɪtri /) is the relationship between the weights of reactants and products before, during, and following chemical reactions. Stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the ...

7. Poisson–Boltzmann equation - Wikipedia

   en.wikipedia.org/wiki/Poisson–Boltzmann_equation

   The Poisson–Boltzmann equation describes the electrochemical potential of ions in the diffuse layer. The three-dimensional potential distribution can be described by the Poisson equation [4] where. ψ is the electric potential. The freedom of movement of ions in solution can be accounted for by Boltzmann statistics.
