Configurational Statistics

Definition

Configurational statistics is the study of the arrangements and distributions of particles or segments in a system, particularly focusing on polymers. It helps in understanding how different conformations of a polymer chain can affect its physical properties, such as elasticity and viscosity, by analyzing the statistical weight of each configuration.
