Ultraviolet and infrared spectral data are reported for a number of benzene ring-substituted nitroindoles and nitroindole-3-carboxaldehydes, and the effect of additional substituents, such as methyl or methoxyl, in the benzene ring is noted. A marked change occurs in the ultraviolet spectra of 4- and 5-nitroindole-3-carboxaldehyde upon replacement of the hydrogen in the 7-position by a larger methyl group. A similar change does not occur in the ultraviolet spectra of the corresponding nitroindoles.
