| intestinal rotation | See: malrotation. Molecular rotation, one hundredth of the product of the specific rotation of an optically active compound and its molecular weight. Optical rotation, the change in the plane of polarization of polarised light of a given wavelength upon passing through optically active substances; measured in terms of specific rotation by polarimetry, an important tool in chemical structural work, especially on carbohydrates. Specific optical rotation ([a]), the arc through which the plane of polarised light is rotated by 1 gram of a substance per milliliter of water when the length of the light path through the solution is 1 decimeter, typically using light corresponding to the D line of sodium.
