The technique of using a pressure‐resisting glass cell for high resolution NMR measurement up to 2000 kg/cm2has been established. The high pressure NMR experiment is shown to be safely conducted on the ordinary high resolution spectrometer. In this report, detailed illustration of the glass cell is described along with the explanation of the device to transmit the pressure, generated in the standard high pressure equipment, to the glass cell located in the high resolution NMR probe.
