+The absolute position of complete temporal overlap of the excitation pulses (zero delay) is a
+crucial step in determining the magnitude of th epeak shift and therefore the total rephasing
+ability of the material. %
+The strategy for assigning zero delay relies upon the intrinsic symmetry of the two-dimensional
+delay space. %
+\autoref{fig:PEDOTPSS_delay_space} labels the six time-orderings (TOs) of the three pulses that are
+possible with two delays. %
+The TO labeling scheme follow from a convention first defined my Meyer, Wright and Thompson.
+[CITE] %
+[CITE] first discussed how these TOs relate to traditional 3PE experiments. %
+Briefly, spectral peak shifts into the rephasing TOs \RomanNumeral{3} and \RomanNumeral{5} when
+inhomogeneous broadening creates a photon echo in the \RomanNumeral{3} and \RomanNumeral{5}
+rephasing pathways colored orange in \autoref{fig:PEDOTPSS_delay_space}. %
+For both phase-matching conditions, there are two separate 3PE peak shift traces (represented as
+black arrows in \autoref{fig:PEDOTPSS_delay_space}), yielding four different measurements of the
+photon echo. %
+Since both 3PE and 3PE* were measured using the same alignment on the same day, the zero delay
+position is identical for the four photon echo measurements. %
+We focus on this signature when assigning zero delay---zero is correct only when all four peak
+shifts agree. %
+Conceptually, this is the two-dimensional analogue to the traditional strategy of placing zero such
+that the two conjugate peak shifts (3PE and 3PE*) agree. [CITE] %
+
+We found that the 3PEPS traces agree best when the data in \autoref{fig:PEDOTPSS_raw} is offset by
+19 fs in $\tau_{22^\prime}$ and 4 fs in $\tau_{21}$. %
+\autoref{fig:PEDOTPSS_processed} shows the 3PEPS traces after correcting for the zero delay
+value. %
+The entire 3PEPS trace ($\tau$ vs $T$) is show for regions \RomanNumeral{1}, \RomanNumeral{3}
+(purple and light green traces) and \RomanNumeral{5}, \RomanNumeral{6} (yellow and light blue
+traces) for the [PHASE MATCHING EQUATIONS] phase matching conditions, respectively. %
+Peak-shift magnitudes were found with Gaussian figs on the intensity level, in accordance with
+3PEPS convention. [CITE]
+The bottom subplot of \autoref{fig:PEDOTPSS_overtraces} shows the agreement between the four traces
+for $T > 50$ fs where pulse-overlap effects become negligible. %
+These pulse-overlap effects cause the 3PEPS at small $T$ even without inhomogeneous broadening.
+[CITE] %
+At long $T$, the average static 3PEPS is 2.5 fs. %

+There is a deviation of the TO \RomanNumeral{1}-\RomanNumeral{3} 3PEPS* trace (green line) from the
+other traces. %
+It is attributed to a combination of excitation pulse distortions and line shape differences
+between OPA1 and OPA2 (see \autoref{fig:PEDOTPSS_linear}) and small errors in the zero delay
+correction. %
+\autoref{fig:PEDOTPSS_traces} shows what the four 3PEPS traces would llike like for different
+choices of zero-delay. %
+The inset numbers in each subplot denote the offset (from chosen zero) in each delay axis. %
+
+\subsubsection{Numerical model} % ----------------------------------------------------------------
+
+We simulated the 3PEPS response of PEDOT:PSS through numerical integration of the Liouville-von
+Neumann Equation. %
+Integration was performed on a homogeneous, three-level system with coherent dynamics described by
+
+\begin{equation}
+ \frac{1}{T_2} = \frac{1}{2T_1} + \frac{1}{T_2^*},
+\end{equation}
+
+where $T_2$, $T_1$ and $T_2^*$ are the net dephasing, population relaxation, and pure dephasing
+rates, respectively. %
+A three-level system was used because a two-level system cannot explain the population relaxation
+observed at long populations times, $T$. %
+This slow delcay may be the same as the slowly decaying optical nonlinearities in PEDOT:PSS.
+[CITE] %
+Inhomogeneity was incorporated by convolving the homogeneous repsonse with a Gaussian distribution
+function of width $\Delta_{\mathsf{inhom}}$ and allowing the resultant polarization to interfere on
+the amplitude level. %
+This strategy captures rephasing peak shifts and ensemble dephasing. %
+
+It is difficult to determine the coherence dephasing and the inhomogeneous broadening using 3PE if
+both factors are large. %
+To extract $T_2^*$ and $\Delta_{\mathsf{inhom}}$, we focused on two key components of the dataset,
+coherence duration and peak shift at large $T$. %
+Since dephasing is very fast in PEDOT:PSS, we cannot directly respove an exponential free induction
+decay (FID). %
+Instead, our model focuses on the FWHM of the $\tau$ trace to determine the coherence duration. %
+At $T > 50$ fs, the transient has a FWHM of $\sim$ 80 fs (intensity level). %
+For comparison, our instrumental response is estimated to be 70-90 fs, depending on the exact value
+of our puse duration $\Delta_t$ (35-45 fs FWHM, intensity level). %
+An experimental peak shift of 2.5 fs was extracted using the strategy described above. %
+Taken together, it is clear that both pure dephasing and ensemble dephasing influence FWHM and peak
+shift so it is important to find valuse of $T_2^*$ and $\Delta_{\mathsf{inhom}}$ that uniquely
+constrain the measured response. %
+

-\clearpage}
+ \label{fig:PEDOTPSS_parametric}
+\end{dfigure}
+
+We simulated the $\tau$ trance for a variety of $\Delta_{\mathsf{inhom}}$ and $T_2$ values. %
+The results for $\Delta_t = 40$ fs are summarized in \autoref{fig:PEDOTPSS_parametric}. %
+The lines of constant $T_2$ span from $\Delta_{\mathsf{inhom}} = 0$ (green left ends of curves) to
+the limit $\Delta_{\mathsf{inhom}} \rightarrow \infty$ (blue right ends of curves). %
+The lines of constant $T_2$ demonstrate that ensemble dephasing reduces the transient duration and
+introduces a peak shift. %
+The influence of inhomogeneity on the observables vanishes as $T_2 \rightarrow \infty$. %
+
+We preformed simulations analogus to those in \autoref{fig:PEDOTPSS_parametric} for pulse durations
+longer and smaller than $\Delta_t = 40$ fs. %
+Longer pulse durations create solutions that do not intersect our experimental point (see
+right-most subplot of \autoref{fig:PEDOTPSS_parametric}), but shorter pulse durations do. %
+[TABLE] summarizes the coherence dephasing time and inomogeneous broadening values that best
+matches the experimental FWHM and inhomogeneous broadening value for $\Delta_t = 35, 40$ and 45
+fs. %
+Clearly, there is no upper limit that can provide an upper limit for the inhomogeneous
+broadening. %
+

+ \begin{tabular}{ c | c c c }

+
+Our model system does ans excellent job of reproducing the entire 2D transient within measurement
+error (\autoref{fig:PEDOTPSS_agreement}). %
+The most dramatic disagreement is in the upper right, where the experiment decays much slower than
+the simulation. %
+Our system description does not account for signal contributions in TOs \RomanNumeral{2} and
+\RomanNumeral{4}, where double quantum coherence resonances are important. %
+In additon, excitation pulse shapes may cause such distortions. %
+Regardless, these contributions do not affect our analysis. %
+
+Extremely fast (single fs) carrier scattering time constants have also been observed for PEDOT-base
+conductive films. [CITES]
