| rotational transform | <radiobiology> \iota = 2PI/q) Due to the combination of applied toroidal field and induced poloidal field, the magnetic field lines wind helically around the torus (and on most flux surfaces they fill the surface ergodically). The rotational transform is a measure of this helicity, and is defined as the average angle the field line shifts in the poloidal direction per complete circuit in the toroidal direction. The quantity q = 2\pi / \iota is known as the "safety factor'' because of its role in stability theory. A magnetic field configuration is said to posses rotational transform if the lines of force, after one complete circuit around the configuration (for example, a torus) do not simply close exactly on themselves, but are instead rotated through some angle about the magnetic axies.

| 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.

| rotation flap |
a local pedicle flap whose width is increased by having the edge distal to the defect form a curved line; the flap is then rotated and a counterincision is made at the base of the curved line, which increases the mobility of the flap. See illustration.
