In rotordynamics, the rigid rotor is a mechanical model of rotating systems. An arbitrary rigid rotor is a 3-dimensional rigid object, such as a top. To orient such an object in space requires three angles, known as Euler angles. A special rigid rotor is the linear rotor requiring only two angles to describe, for example … See more The linear rigid rotor model consists of two point masses located at fixed distances from their center of mass. The fixed distance between the two masses and the values of the masses are the only characteristics of … See more For a long time, molecular rotations could not be directly observed experimentally. Only measurement techniques with atomic resolution made it … See more • D. M. Dennison (1931). "The Infrared Spectra of Polyatomic Molecules Part I". Rev. Mod. Phys. 3 (2): 280–345.

This paper deals with the effects of a superimposed radial outflow upon the motion of the fluid between a rotating and a stationary plane disc. This is an idealisation of the situation found in advanced turbo-machinery in which cooling of the rotor faces is necessary.
