A technique for the obtaining of the energy signal and, thus, the IR spectra is described. The technique is simple and sensitive and allows the observation of high frequency vibrational bands. The technique utilizes a silver bromide disc as a sample holder set in a diffuse reflectance attachment. Spectra of O-nitroaniline 1-tetra-decanol, and copper phthalocyanine green are presented. Possible applications of the technique include compound identification and FT-IR analysis of HPLC effluent.
