Breit equation

The Breit equation is a mathematical formula that describes how two atoms or molecules interact with each other. It helps scientists understand how different atoms and molecules interact and can be used to make predictions about how reactions will take place. Imagine two people standing next to each other. The Breit equation is like a set of instructions that tells scientists how these two people will interact, and how far away from each other they should stay in order to avoid any problems.
