Interest in spectral hole burning comes from its potential application as high density computer memory. An external electric field can be used to shift the spectral holes so as to obtain an even larger number of detectable holes than with the excitation wavelength alone. 

The chapter is divided into five sections. In Sec. Ill, we discuss how the molecular structure of crystal violet (CV), which is one of TPM dyes selected, is sensitive to its surrounding solvent molecules in solution. Recently, subtle structural differences in the ground state of CV was identified in alcohols by means of a femtosecond spectral hole-burning technique [19-21], Two key points of these studies are (1) proposal of a novel class of isomers, which are differentiated from one another by solvation and (2) conclusive decision of a long-run dispute over 50 years on whether the ground-state conformational isomers exist. 

Many studies concluded that only D3-symmetry is possible and denied C2-symmetry structures. However, the authors failed to explain the temperature and pressure dependence of the absorption spectrum as the substantial evidence for two ground states. On the other hand, only the temperature and the pressure dependence of the absorption spectrum evidenced the two ground states. Thus, no one has proposed any models of explaining comprehensively all the previous experimental observations and theoretical calculations. We found a convincing model of CV involving two ground states from experimental observations favored by tunable-excitation femtosecond spectral hole-burning technique and theoretical calculations. 

Local non-uniformities present the danger of hot spot formation where the current forms filaments. Two adverse scenarios can develop (1) local thermal run away that engenders regions of high defect density which gradually grow in size, and (2) spectral hole burning in which certain spectral modes are locally depleted. For all of these reasons, uniform material properties have always been a mandatory virtue.
