optical rotation
This term is a specialized technical expression used primarily in chemistry, physics, and pharmacology. It describes a specific physical property of chiral molecules, where the substance acts as a medium that shifts the orientation of light waves. It is almost exclusively used in scientific reports, laboratory settings, and academic textbooks.
Because it refers to a specific physical phenomenon or a measured value, it is treated as an uncountable noun. You would refer to "the optical rotation of a sample" rather than "an optical rotation," unless specifically discussing different types or instances of the phenomenon in a comparative theoretical context.
