Abstract
The spectral region from the photographic limit at 1.2 $\mu$ to about 3 $\mu$ now accessible through the use of photoconductive cells, is of considerable importance for the elucidation of atomic spectra, especially those of neutral atoms, which often have some essential transitions in this region. This will be illustrated by results obtained in recent investigations of some elements in the first, second and third columns of the periodic system. Also, we shall briefly describe the method of measurement and the special precautions that have made it possible to attain a wave number accuracy of $0.01 cm^{-1}$ with a Pfund type grating spectrograph of one meter focal length and an uncooled leadsulphide cell.
