Figure 2

The fitted parameters as dependent on the delay (the starting point of evaluation— 𝑡 0 ) obtained for the delay of anthracene in cis/trans-DMCH at 146 K for middle excitation pulse. Part (a): first-order rate constant 𝑘 𝑇 : squares ( 𝑘 d f , e 𝑇 )—delayed fluorescence, exponential fit (21); circles ( 𝑘 d f , n e 𝑇 )—delayed fluorescence, nonexponential fit (17); solid line ( 𝑘 p h , e 𝑇 )—phosphorescence, exponential fit; dashed lines—accuracy of 𝑘 p h , e 𝑇 ; dash-dotted line ( 𝑘 p h , n e 𝑇 )—phosphorescence, nonexponential fit; dash-dot-dotted lines—the accuracy of ( 𝑘 p h , n e 𝑇 ). Part (b): main plot indicator of nonexponential ( 𝑃 4 ) behavior; right inset: comparison of smoluchowski parameter   ( 𝑃 2 ) for nonexponential fit (lower curve) and exponential fit (upper curve); left inset: autocorrelation function for nonexponential fit (lower curve) and exponential fit (upper curve).
