Or to take things to the opposite extreme, on the quantum scale the photon interacts with something and changes its orbital or spin quantum number and the angular momentum seems to just mean a transition in a molecule.

Where is the spin component along the-axis ( either,, or ), is the spin projection quantum number along the-axis, and is the principal spin quantum number ( discussed in the previous section ).
33.
The azimuthal quantum number is the second of a set of quantum numbers which describe the unique quantum state of an electron ( the others being the principal quantum number, following spectroscopic notation, the magnetic quantum number, and the spin quantum number ).
34.
Each atomic orbital is described by a set of quantum numbers, but electrons have an additional quantum number, so-called spin quantum number, which for an electron can take two possible values ( 1 / 2 or-1 / 2 ).
35.
In the context of the Dirac equation and Weyl equation, the Weyl spinors satisfying the Weyl equation transform under the simplest irreducible spin representations of the Lorentz group, since the spin quantum number in this case is the smallest non-zero number allowed : 1 / 2.
36.
In practice, spin is given as a dimensionless " spin quantum number " by dividing the spin angular momentum by the reduced Planck constant, which has the same units of angular momentum, although it should be noted that this is not the full computation of this value.
37.
Height-Width-Length is a nice three-part set, the problem with using it is that those three words already apply to a part of physical reality which is already " coded for " in the x-y-z axis system inherent in the particle spin quantum number.
38.
However, unlike orbital angular momentum in which the " z "-projection quantum number " " can only take positive or negative integer values ( including zero ), the " z "-projection spin quantum number " s " can take all positive and negative half-integer values.
39.
For the case of a symmetric diatomic with nuclear spin quantum number " I " for each nucleus, there are ( I + 1 ) ( 2I + 1 ) symmetric spin functions and I ( 2I + 1 ) are antisymmetric functions for a total number of nuclear functions g ^ { ns } = ( 2 I + 1 ) ^ 2.
