Molecular Rotation

Molecular rotation refers to the way molecules spin around their axes, similar to how a spinning top turns. Even tiny molecules are in constant motion, and this rotational energy impacts how they absorb and emit light. These rotations depend on the molecule’s shape and mass distribution and influence their temperature and behavior in gases or liquids. By studying molecular rotation, scientists can gain insights into molecular structure, interactions, and energy levels, which are fundamental for understanding chemical reactions and physical properties at the microscopic level.
