Abstract

A step-and-integrate Fourier transform spectrometer, a liquid-helium-cooled composite germanium bolometer, and specially configured non-focusing optics have been interfaced to gasketed diamond anvil cells. Simple molecular solids like iodine have been studied at pressures up to 16 GPa, frequencies down to 20 cm⁻¹, and temperatures of 2 to 150 K with this arrangement. Evidence that spectroscopy in diamond anvil cells should be feasible to even lower frequencies and higher pressures is presented.
