Figure 4
Spectra of the imaginary part of the dielectric anisotropy between (a) the b- and c-axis directions, (b) the c- and a-axis directions and (c) the a- and b-axis directions of the monoclinic sample crystal, calculated from the spectra of ellipticity and rotation of polarization, and the Kramers–Kronig (K–K) transforms of the imaginary part of the dielectric anisotropy. The left and right ordinates of each graph are shifted for clarity and are drawn on the absolute scale of relative dielectric constant. |
