A systematic study of the integrated intensity of the IR bands of butadiene (C4H2), developed to overcome the discrepancies between the published values of band intensities for diacetylene, is described. The obtained values, given with error bars, are reported and compared to the literature data. In addition, absolute IR band integrated intensities (from 2.5 to 45 micrometers) were measured in the laboratory for benzene, and cyanoacetylene from 220 up to 320 K. From this an idea of the intensity versus temperature was obtained. In particular for the nu4 band of benzene (14.8 micrometers) and for several fundamental bands of cyanoacetylene, an accurate empirical formula which provides the value of integrated band intensity and a function of temperature was deduced.
