The pressure dependence of the Raman spectra of was investigated up to 15.5 GPa. The anti-ferrodistortive SrTiO 3 cubic-tetragonal phase transition (phonon condensation at the R point of the Brillouin zone) occurs at about 6 GPa. The strong, broad bands, present under ambient conditions, sharpen and
Phosphorescence spectra of benzophenone have been investigated with a diamond anvil cell. At 2 K the spectra remain sharp under high pressure. The pressure shift of the origin exhibits a plateau around 25 kbar. This and other spectral observations are interpreted.
