CCL: Query on radiative decay rate constant formula

Hi Elizabeth,
  It seems their relationship is (2.5x10^5 x c^3) / pi x epsilon
  This formulation is unknown, at least to me, but it seems this implies a
 different radial decay, perhaps related to a perturbated condition of some sort.

  Sent to CCL by: "Eli Lam" [elizabeth.shlam _ gmail.com] Dear CCLers,
 I have been reading papers on radiative decay rate constant. In general, people
 start of with the formulae: ((16x10^6 pi^3 E^3) /3h(epsilon))* (transition
 dipole moments), where h is the Planck's constant, epsilon is the vacuum
 permittivity, and E is the excitation energy, (Inorganic Chemistry, 42, 20,
 2003). Yersin starts with the formulae: (64pi^4 E^3 / 3hc^3) *(transition dipole
 moments), where c is the speed of light (Coordination Chemistry Reviews 255,
 2622, 2011). I would like to ask 1) How is the two formula related? 2) How is
 these two formula derived? Thank you very much! Elihttp://www.ccl.net/cgi-bin/ccl/send_ccl_messagehttp-:-//www.ccl.net/chemistry/sub_unsub.shtmlhttp-:-//www.ccl.net/spammers.txt--========GMXBoundary220991359109139981905
