Abstract

The absorption spectrum of atomic iodine has been investigated in the spectral range $λ 2100$ to 1400Å. The iodine was dissociated by heating to 1000°C. A hydrogen discharge tube or an iodine discharge tube was used as the source of illumination. The former source revealed clearly that $λ 1830$ and 1783Å are absorption lines. When light from a discharge in iodine was passed through the heated iodine the following lines were found to be weakened by absorption, $λ 1830$ , 1783, 1642, 1618, 1583, 1515, 1507 and 1422Å.
