Triplet
The triplet represents bunching terms that are
exponential decay functions.
You can select the triplet term in their normalized
form by checking the Normalized check box or in
their non-normalized form by unchecking the box
(Fig. 281).
You can choose, if you want to the bunching
terms to be weighted or not by checking or
unchecking the Weight box. If no weights are
applied, the fit follows the measured curve to
minimize Χ 2
. If no boundary values are set for the
relaxation times, noise might also be followed and
triplet fractions might show up to be too high. If
weights are applied, noise is followed less. The
following weight equation is used:
t ( i )
−
= +
Weight ( t ) 1 10
You have several options for the bunching terms
which you can select by the Components drop
down menu:
Triplet: 1 exponential function
Blinking: 1 exponential function
Independent Triplet and Blinking: Sum of 2 expo-
nential functions
Dependent Triplet and Blinking: Product of 2 expo-
nential functions (Fig. 282)
The name of the selected term is shown in the
Components display box.
The description box gives information on the
bunching terms.
