Analysis of Distance Distribution from Time-Domain Measurements

Analysis of Distance Distribution from Time-Domain Measurements 

The procedure for recovery of the.jj tance distribution from the TD data is analogous to dfat used for the FD data. The intensity at any tnae is described by Eq. [14.4]. This dec law is used with the convolution int ral and the measured insuument response function, fft), to obtain calculated values of fiu(r) for any given tune tj. 

Equation [14.21] can be undostood as the intensity at tnne tj b g the sum of the intensities due to excitation a series of 5-fonctions which, in total, lepresent the li t pulse Z r). 

These calculated values are then compared to the meas-ined data /o (r) to mioiinize The experimental /n (0 data are a coovololioD of the impulse response function WO with the instrument function l(t). As for the FD measurements, a separate measurement of the donor decay is needed, and this decay law is held constant in the distance shslribution analysis. 

D-A aoDToacfa fr-i.) or a maximum D-A distance (r u) that is allowed by the expoimental data. If such and tmu ate used, then one must be catefid to ncmnalize the P(r) function to unity.
