Raman spectra of shock compressed pentaerythritol tetranitrate single crystals: Anisotropic response
Article Abstract:
Single-pulse Raman spectroscopy is used to examine the response of crystals shocked along the [100] (insensitive) and [110] (sensitive) orientations to gain insight into the anisotropic sensitivity of shocked pentaerythritol tetranitrate (PETN) single crystals. The data in combination with previous static pressure results provide support for conformational changes in PETN molecules for shock compression along the [110] (sensitive) orientation.

Raman and X-ray scattering of high-pressure phases of urea
Article Abstract:
A series of Raman-scattering measurements on urea in a diamond-anvil cell at room temperature, at pressures up to 12 GPa is reported. It is suggested that the spatial domains consist of regions with varying crystallographic orientations or varying directions of electric polarization.

High-pressure effects on fluorescence of anthracene crystals
Article Abstract:
Pressure-induced changes on the fluorescence spectra of anthracene crystals are examined up to 5 GPa. Under hydrostatic pressure, there was no excimer fluorescence from anthracene single crystals.
