 Title: THE INTENSITIES AND SHAPES OF INFRARED ABSORPTION BANDS IN LIQUIDS AND SOLUTIONS Creators: Ramsay, D. A.; Jones, R. N. Issue Date: 1951 Publisher: Ohio State University Abstract: Three methods will be described for the experimental determination of the absolute intensities of infrared absorption bands in liquids and solutions. These methods are dependent on a knowledge of the true shape of the absorption band, which may be approximated satisfactorily by a Lorentz equation. The first method involves direct integration of this equation, a correction factor being applied for the effect of finite slit width. The other methods involve extensions of the extrapolation procedures used by Wilson and Wells and by Bourgin. Assuming a Lorentz band shape and a triangular slit function, the natures of these extrapolations may be calculated for various experimental conditions. Applications of these methods to the measurement of carbonyl intensities in steroids will be discussed. Description: $^{\ast}$ Now with Division of Physics.
