	Degrees of freedom (physics and chemistry) - Wikipedia, the free encyclopedia
		Degrees of freedom is a general term used in explaining dependence on parameters, and implying the possibility of counting the number of those parameters.
		It is notable that not all degrees of freedom of the hydrogen molecule participate in the above expression of its energy.
		Since the degrees of freedom are independent, the internal energy of the system is equal to the sum of the mean energy associated to each degree of freedom, which demonstrates the result.

	Wikinfo \| Degrees of freedom
		The phrase "degrees of freedom" is used in three different branches of science: in physics and physical chemistry, in mechanical and aeronautical engineering, and in statistics.
		In physics and chemistry, each independent mode in which a particle or system may move or be oriented is one degree of freedom.
		According to thermodynamics, each degree of freedom in every particle of a system will contain the same energy on average (equal to kT, the temperature of the system multiplied by the fundamental Boltzmann constant).

	Infrared Spectroscopy and Degrees of Freedom
		There is one degree of freedom per independent mode of motion, ie., translational (rigid "whole body" movement in the x, y or z directions), rotational (whole body rotation around one or two independent axes) or vibrational (oscillation of bond length or angle).
		An atom, as a point object, cannot have rotational degrees of freedom: a point object has no dimension and hence no moment of inertia (nothing to rotate about an axis).
		Besides its three translational and one vibrational degrees of freedom, a diatomic molecule can only rotate rigidly about its center of mass, since it has no cross sectional dimension (a bond is idealized as having no thickness).
