In 1961 the International Union of Pure and Applied Chemistry (IUPAC) formulated calibration standards for wavenumber measurements in the infrared, but comparable standards for infrared intensity measurements are still not available. In 1985 IUPAC established a Working Party on Secondary Standards for Intensity Measurements in Infrared Spectroscopy. This project is now a stage where it is desirable to solicit advice and experimental support from a wider circle of spectroscopists in anticipation that a specific set of infrared intensity standards and calibration procedures could be formulated for measurements in the liquid phase. This paper outlines the background of these studies and reviews the present status of the project.
