✦ Synopsis

The influence of spectrometer slit-widths and concentration of solutions upon the shapes of infra-red absorption bands of the carbonyl stretching vibrations has been examined. The apparent band widths, apparent extinction coefficients at band peaks, and integrated intensities of the carbonyl band of acetophenone and propiophenone in chloroform solutions were measured under different conditions.

The experimental results are compared with those calculated using the procedure previously worked out by RAMSAY. Some general conclusions have been drawn about the diaculties of determining the characteristic quantities of i&a-red absorption bands.

The intrinsic intensity of the 0=0 infra-red band has been measured for various halogenated acetic acid derivatives dissolved in carbon tetrachloride. For reference purposes, formic and acetic acids were studied. D-Oarboxydichloroacetic acid was also measured. For measurement of the intensity, WILSO
