The absorption spectrum of the \emph{B} $\leftarrow $ \emph{X} transition of molecular iodine has been recorded at Doppler resolution, in the region 14500 - 20000 cm$\mathrm{<mrow\; data-mjx-texclass="ORD">-1</mrow>}$, on a Fourier transform spectrometer. Calibration has been checked against the Doppler-Free High Resolution Spectral Atlas of the Iodine Molecule} across the region common to both spectra. Our version of the iodine atlas, which was originally produced at Orsay,}$, ed. CNRS (1978)} avoids the need for systematic wavenumber corrections} 791 (1979)} to short-wavelength peaks, and should be compatible with any software. It has proved a convenient tool in our laboratory, and we hope others may also find it useful. The transmission spectrum is available, on request, as a single ascii file.
