The origin of fluorescence is at 18332 cm-1 and is b-polarized. Comparing the origin of fluorescence and absorption (see Fig. 6-8) we notice that, although both... 

Figure 6-6b. b- anil c-polanzed absorption spectra of T(, single crystal at 4.2 K extended to higher energy. Above 21 U00 cm-1 the b-polarized spectrum shows broad bands which are discussed and assigned in the text (Section 6.4.1), while in c direction the light is completely absorbed. 

The b-polarized absorption bands (see Fig. 6-3b) at 20945 cm 1, 22250 cm-1 and 23535 cm-1 are assigned to a vibronic progression built on the bu Davydov component with the totally symmetric mode at 1275 cm-1. 

Several b-polarized sharp bands are assigned as ground slate totally symmetric vibrations at 699, 738, 1056, 1369, 1460 and 1504 cnT1 built on the fluorescence origin (see Fig. 6-18). These modes are in excellenl agreement with those obtained from the single crystal Raman spectra thal we measured exciting at 1064 and 632.8 nm [35].

Gain margin (GM) is defined as the reciprocal of the intersection of the G B polar plot on the negative real axis. 

The Bode plot of this combination of an integrator and a first-order lead is shown in Fig. 13.13h, At low frequencies, a PI controller amplifies magnitudes and contributes —90° of phase-angle lag, This loss of phase angle is undesirable from a dynamic standpoint since it moves the Gj B polar plot closer to the ( — 1,0) point.
