Spatial Distribution

Definition

Spatial distribution refers to the arrangement and organization of particles, molecules, or phenomena across a given space. In the context of interstellar molecules, understanding spatial distribution is essential for determining where certain molecules exist within space and how they relate to their surrounding environments, such as star-forming regions or molecular clouds.
