solvation dynamics

Solvation dynamics refers to how solvent molecules (like water) respond and reorganize around a solute (such as a dye or ion) when it changes state, like when it gets excited or reacts. Imagine a group of people (solvent molecules) adjusting their positions around a person (the solute) to accommodate a new situation. This process involves the solvent molecules moving and reorienting, which can affect the properties and behavior of the solute. Studying solvation dynamics helps us understand molecular interactions and the time scales involved in these adjustments, important in fields like chemistry and biology.
