Spectroscopic notation is based on symmetry considerations.
We shall see in Section 5.7 that symmetry considerations allow us to decide which vibrational modes will lead to Raman scattering.
In this case we may use different colors to keep track of the cycles, although symmetry considerations will work as well.
(By symmetry considerations, a round sphere will remain round under this flow, so that the radius at time determines the surface at time .)
Recently, an alternative explanation of magic numbers has been given in terms of symmetry considerations.
The only component of the electric field is in the z direction (the others must be zero by symmetry considerations).
Here the word 'random' must be interpreted as subject to correct symmetry considerations.
The O nucleus has zero nuclear spin angular momentum, so that symmetry considerations demand that N may only have odd values.
All of those regimes can at once be described with the help of the single microscopic theory the selection rule find their origins that in symmetry considerations.
Ferroelectric materials are required by symmetry considerations to be also piezoelectric and pyroelectric.
