Discussion Overview

The discussion revolves around the simulation of electromagnetic fields around atoms and materials, particularly in the context of understanding the forces that drive chemical reactions. Participants explore the relationship between electromagnetic forces, quantum mechanics, and molecular modeling.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant inquires about software that simulates electromagnetic fields around atoms and materials to understand chemical reactions.
  • Another participant suggests that existing programs for molecular modeling do not align with the initial inquiry, emphasizing the role of quantum mechanics in describing atomic and molecular behavior.
  • A participant challenges the assertion that electromagnetic forces drive chemical reactions, suggesting that stability is better explained through electrostatics and requires solving Schrödinger's equation.
  • Another participant argues that quantum mechanics can often be simplified into classical mechanics for simulations, implying a more straightforward approach to modeling.
  • A later reply directly contests the idea that quantum mechanics can be simplified in this context.

Areas of Agreement / Disagreement

Contextual Notes

Participants highlight the complexity of accurately modeling atomic interactions and the necessity of understanding charge distributions, which may depend on various assumptions and definitions related to quantum mechanics and electrostatics.

hello
is there a software that simulates electromagnetic field around atoms, materials?
to simulate the forces that drive chemical reactions?
thanks!

Probably not the way you think. There are programs for molecular modeling like

https://en.wikipedia.org/wiki/Spartan_(software)

Please note it is not about "electromagnetic field around atoms, materials", it is about quantum mechanics. QM is what describes behavior of atoms and molecules.

And this is not exactly about predicting possible reactions, although these things are never far away from molecular modeling.

what do you mean it's not what I think?

isn't electromagnetic forces that drive a chemical reaction?

I wouldn't say that.

Stability of the molecule can be explained using pure electrostatics. However, to do so, you have to calculate first what is the charge distribution. To do so, you have to solve Shroedinger's equation. You can't explain what is going on without quantum mechanics, which are only part of the problem.
 
but in most cases quantum mechanics are simplified into simple mechanics when we are doing simulations, or at least you can solve quantum mechanics equations to simulate, but the principle of the simulation is regular mechanics

No.
