The transition rate decreases by a factor of about 1000 from one multipole to the next one, so the lowest multipole transitions are most likely to occur. interval0to40onan&92;atomic"grid. Each of these, being electromagnetic radiation, multipole transitions e1 atomic consists of an electric and a magnetic field.

Semi-forbidden transitions (resulting in so-called intercombination lines) are electric dipole (E1) transitions for which the selection rule that the spin does not change is violated. Electric dipole transition is the dominant effect of an interaction of an electron in an atom with the e1 electromagnetic field. multipole transitions e1 atomic At that mul­ti­pole level, ei­ther the elec­tric or the mag­netic term can be nonzero, de­pend­ing on par­ity. The relationships between A, f, and S for electric dipole (E1, or allowed) transitions in SI units (A in s-1, λ in m, S in m 2 C 2) are ( 19 ) Numerically, in customary units ( A in s -1, λ in Å, S in atomic units),.
