• An infrared ATR apparatus for use at low temperatures was constructed for the determination of the optical constants and absorption intensities of crystalline samples. The ATR spectra of benzene and carbon disulfide polycrystals were measured with two different incident angles. The optical constants and then the absorption intensities were accurately obtained for the fundamental bands from these ATR spectra. Experiments for transmission spectra were also carried out with an improved absorption cell at low temperatures, confirming the present ATR results. A comparison of the intensities in different phases was made for the ν<SUB>18</SUB>, ν<SUB>19</SUB>, ν<SUB>20</SUB>, and ν<SUB>11</SUB> fundamental bands of benzene and the ν<SUB>3</SUB> band of carbon disulfide.
