    • The time-dependent red shift is also known as the fluorescence dynamic Stokes shift, Time-resolved fluorescence spectroscopy as well as pump-probe transient gain/absorption spectroscopy and three-pulse photon echo techniques can be used to gain information about microscopic dielectric relaxation in the environment of a solvatochromic fluorophore

    • The term monoexponential is used throughout this paper to describe a fluorescence kinetic curve or a decay curve f(t) that equals zero before δ-excitation at t, 0 and equals α exp(-t/τ) at t > 0, i.e, f(t, αθ(t) exp(-t/τ, where θ(t) denotes the Heaviside step function. The terms non-monoexponential and multiexponential are both antonyms of monoexponential, although in theory they have different meanings. Since any fluorescence kinetic curve can be adequately represented by a linear combination of a finite number of exponential terms the number of required terms depending on the data quality, from the practical point of view any non-monoexponential curve is also a multiexponential curve and vise versa

    • The number of degrees of freedom equals the number of channels where photon counts are stored minus the number of fitting parameters. For global fitting the number of channels per kinetic curve must be multiplied by the number of kinetic curves; this product less the total number of all (global, local) fitting parameters equals the number of degrees of freedom
