In order to extend the data available for the identification of carbonyl compounds, the x-ray powder diffraction patterns of sixty-four 2,4-dinitrophenylhydrazones of aldehydes and ketones were determined. An alphabetical table includes 39 additional compounds found in the literature. A second numerical table indexes the spacing and intensities of the three strongest lines in Hanawalt groups. The complete new diffraction pattern data are available from the American Documentation Institute.
