“…The pressure-dependent shift is related to the local compressibility of the crystal, and the pressure-dependent broadening in principle contains information about the nature of inhomogeneous broadening in this system. Although experimental data for pressure-dependent broadening in crystals have yet to be analyzed, a possible theoretical model for this effect has just appeared …”

Optical spectroscopy provides a useful tool for probing the structure and dynamics of solids. Over the years, optical methods have evolved from absorption spectroscopy to more complex methods such as spectral hole burning, photon echoes, and luminescence line narrowing. The absorption spectrum provides information about inhomogeneous broadening, while the latter approaches provide information about the systematics of the homogeneous line shapesinformation that is often obscured by inhomogeneous broadening. When external perturbations such as strain or electric fields are applied, details of the local site can be obtained. Recently, the ultimate limit of optical spectroscopy has been attained, in which the spectral properties of individual single impurity molecules in a solid can be measured, with all ensemble averaging removed. This novel regime has provided additional, previously unobtainable, information on a highly local scale, such as the direct observation of the spectral shifting of a single molecule produced by configurational transitions of the host. It is to be expected that further surprises await us in this new frontier of single-molecule spectroscopy in solids.

THE REVIEW OF HIGH PRESSURE SCIENCE AND TECHNOLOGY

We present a review of our studies of persistent spectral holes mainly in chlorin-doped polystyrene, frozen n-octane and p-terphenyl under pressures up to 8.4 kbar at 4.2-15 K in isobaric-isothermal experiments. In polystyrene and n-octane, narrowing of holes under pressure was observed and interpreted by the pressure dependence of lowfrequency pseudolocal vibrations. In p-terphenyl a drastic increase in holewidths was detected in the phase transition region around 5.5 kbar at 4.2-14 K.
