The low‐frequency Raman spectra of gaseous formic and acetic acids are corrected from counts per second to the square of the polarizability derivative with respect to the normal coordinate. The acetic acid peak at 98.9 cm −1 is shifted to 106 cm −1 by this correction, necessitating minor reassignments. The intense, broad, 'Rayleigh Line' is greatly reduced by this correction, to reveal scattering by pure rotational motion.
