1. A basic, phenomenological understanding of the transition dipole moment can be obtained by analogy with a classical dipole.
2. In addition, the transition dipole moment depends on the geometries and relative phases of the initial and final states.
3. Let's say we want to calculate transition dipole moments for an electron to transition from a 4d to a 2p subshell.
4. For example electric dipole which in turn are excited by optical phonons or fluid particle vibration, or transition dipole moments of electronic transitions.
5. The dot product includes a factor of \ cos \ theta, where \ theta is the angle between the polarization of the light and the transition dipole moment.
6. It's difficult to find transition dipole moment in a sentence. 用transition dipole moment造句挺難的
7. The probability is proportional to the square of the amplitude of the radiation field, E 0, and the square of the transition dipole moment | ? if |.
8. When an atom or molecule interacts with an electromagnetic wave of frequency \ scriptstyle { \ omega }, it can undergo a transition from an initial to a final state of energy difference \ scriptstyle { \ hbar \ omega } through the coupling of the electromagnetic field to the transition dipole moment.
9. Similarly, the coupling between an electromagnetic wave and an atomic transition with transition dipole moment \ scriptstyle { \ mathbf { d } _ { nm } } depends on the charge distribution within the atom, the strength of the electric field, and the relative polarizations of the field and the transition.
10. where \ omega is the emission frequency, n is the index of refraction, \ mu _ { 12 } is the transition dipole moment, \ varepsilon _ 0 is the vacuum permittivity, \ hbar is the reduced Planck constant, c is the vacuum speed of light, and \ alpha is the fine structure constant . ( This approximation breaks down in the case of inner shell electrons in high-Z atoms . ) The above equation clearly shows that the rate of spontaneous emission in free space increases proportionally to \ omega ^ 3.
