steric
This term is used exclusively within the fields of chemistry and molecular biology to describe the physical bulk of atoms. It refers to the spatial constraints that occur when atoms are positioned so closely that they repel each other, thereby influencing how a molecule reacts or folds.
In a professional scientific register, it is most frequently paired with "hindrance" or "effects." It is not used in general conversation to describe physical space or architecture, as its application is strictly limited to the sub-microscopic scale of molecular geometry.
