The evaluation of the transition probability or the electron number from absorption measurements is difficult for weak bands with background absorption. Here the formulae are developed to evaluate this quantity from the difference in height of maximum and minimum of the dispersion curve.

  1. For literature, see the following paper by Pittman.
  2. It seems to me that at least for the infra-red, where the absorption is due to the oscillation of known masses the quantity b would have more physical meaning if we take the effective charge as e √ƒ and leave m′ unchanged.
