Measurement Techniques under High Pressure

Analyse thermique différentielle; differential thermal analysis

Analytical technique involving monitoring the temperature difference between the sample under study and an inert control body.

Diffraction; diffraction

Deflecting the propagation of waves when they encounter an obstacle, a liquid or solid body.

Spectrométrie infrarouge; infrared spectrometry

Measurement of a substance's absorption of infrared radiation that modifies the vibrational energies of the substance's interatomic bonds.

Spectrométrie Raman; Raman spectrometry

Measurement of the inelastic scattering (interaction with energy exchange) of monochromatic radiation by a substance, using in particular the frequency shift of lines related to the vibrational...
