 Force field (chemistry)

In chemistry, a force field refers to a set of mathematical functions and parameters used to describe the potential energy of a system of particles, typically atoms and molecules. Force fields are critical in molecular modeling and simulations, particularly in computational chemistry and molecular dynamics. They allow scientists to predict the physical behavior of molecules, including their structure, dynamics, and interactions. A force field typically includes: 1. **Bond Stretching**: Describes the energy associated with changes in bond lengths between atoms.
