Abstract : New values are reported for the positions of the absorption maxima in the infrared spectrum of indene containing 0.8% by weight of both camphor and cyclohexanone. The personal error in locating the maxima has been reduced by fitting polynomial series of the second, third and fourth degrees through five points in the neighborhood of the maxima, and computing the roots of the first derivatives, using a computer technique previously described. The peak values are compared with independent measurements made by P. J. Krueger on a different spectrometer. The peaks most suitable for calibration purposes have been selected on the basis of their distribution in the spectrum and the low r.m.s. variation in the computed positions of the maxima.
