<p>PURPOSE:To obtain certain information relation to the molecular orientation of a membrane, by performing infrared spectrophotometric measurement using a specimen which is obtained by forming a solid membrane having a thickness permitting the transmission of a part of infrared rays on a monocrystalline silicon substrate and further forming a membrane for obtaining an infrared absorption spectrum on said solid membrane. CONSTITUTION:A specimen is formed by forming a platinum membrane 6 on the main surface of a monocrystalline silicon substrate 5, to which mirror surface finish has been applied, by sputtering or vapor deposition and depositing a membrane 2 composed of a substance desired to obtain an infrared absorption spectrum to the surface of the membrane 6. Thereafter, the transmitted spectrum is measured and, further, the specimen is used as it is to measure a reflected spectrum. Therefore, both of transmitted and reflected spectra can be measured using the same specimen as it is and, as a result, the accuracy of information obtained by the comparison of both spectra can be increased without considering the difference of the specimen. Further, a specimen that is a combination of a large number of substances can be formed and information useful for molecular orientation is obtained.</p> |
