Abstract
The pressure dependence of the 795 cm−1 mode of quartz has been measured in the infrared up to 20 GPa at 300 and 400 K. For the measurements, which are impossible with a laser light, on photo sensitive or biological samples, we propose to use the pressure dependence of this mode as a pressure gauge.
