  • Patterson , L.K. private communication Fluorescence lifetime measurements of chlorophyll a in monolayers of lipids in the presence of vitamin K show Stern-Volmer behaviour when vitamin K concentration is varied. The quenching is though to occur by energy migration among chlorophyll pigment molecules, followed by trapping at a closely spaced pair of molecules comprised of one chlorophyll and one vitamin K molecule, and within which electron transfer occurs.

  • The Marquandt algorithm was used to get a least-squares fit of the decays to equation (18). The quantity Х2 v is the reduced chi-square defined as and v is the number of degrees of freedom.
  • The 1/e lifetimes of [4(b)] corresponds to flourescence decays including a monomolecular rate of 1 ns−1. By multiplying our own trapping decays φ(t) by exp (−t), we obtain the corresponding flourescence decays and can select the one with the 1/e flourescence lifetimes in the range of the ones of [4(b)].
  • The authors of [4(a)] give n=0·5±0·2 for the trapping decays, but according to their figure 1, the fitting seems to have been done over a much longer time interval. In [4(b)], the value of n=0·3±0·2 has been averaged over three dacays only. Moreover, Monte Carlo simulations are less accurate than solving numerically the associated master equation.
