INFRARED spectroscopy has been successfully applied to a multitude of qualitative and quantitative analyses and investigations in the fields of chemistry and physics over a period of several years. Infrared spectroscopic studies in the fields of medicine and biology are of recent inception, by way of comparison. Pigmented skin tumors were examined in the infrared spectrometer during the course of this investigation, the objective of which was to study the infrared transmission and absorption of these lesions in the region of 2 to 16 μ. In succeeding paragraphs will be presented first an introduction to the subject of infrared spectroscopy, followed by an account of its use in the study of pigmented skin tumors.
The infrared spectrometer is a physical tool which is used for measuring and recording the infrared transmission and absorption of solids, liquids, and gases,1 while the procedure itself is referred to as
