Photothermal deflection spectra

Fig. 2.9 Photothermal deflection spectra of PFB (black), F8BT (red), and a PFB F8BT blend film (green) The weight ratio of the blend was 90 10, and it was spun from chloroform.

Figure 16 Photothermal deflection spectrum of a NH3 -compensated trans-VA. Dots and dashed line show the absorption edge recorded on two films, 4 p.m and 0.1 xm, respectively. Dotted line shows the residual absorption of an uncompensated sample. Solid line sketches the expected neutral soliton absorption in the absence of electron correlation. (From Ref. 130.)...

FIGURE 8.5. Absorption spectrum of a ladder-type PIPP as determined by conventional UV/vis transmission spectroscopy (dashed line) and photothermal deflection spectroscopy (PIDS, solid line) the dotted line shows the intensity of the PIDS pump beam. (Reproduced from Ref. 160.)... 

Figure 9-13. Absorption spectrum of mLPPP, determined using photothermal deflection spectroscopy (PDS) - from Ref. [143].

Figure 18.2 [a] Amplitude and [b] phase vs. frequency curves measured with the photothermal excitation in water. The PSD spectrum of the deflection signal measured without cantilever excitation is superposed on the amplitude curve obtained with the driven cantilever In (a). The values for Q and /o obtained from the thermal PSD spectrum are 8.7 and 157.079 kHz, respectively. The dotted line in [b] is calculated with these parameters, while the solid line shows the experimentally measured values. ...
