ÅNGSTRÖM, Anders Jonas (1814-1874). Recherches sur le spectre solaire [Atlas contenant les longeurs d'onde des raies Frauenhofériennes données en 1/10,000000 de millimètre]. Uppsala: W. Schultz, 1868.
2 volumes (text and atlas), 4° (310 x 240mm) and oblong 2° (320 x 500mm). 6 lithographic plates after R. Thalén (1827-1905), Ångström's laboratory assistant, with separate title. (Title and first plate with marginal soiling, some tape repairs.) Text with lithographic frontispiece showing Ångström's spectrometer. (Occasional insignificant marginal spotting.) Atlas contained within modern half cloth portfolio, original printed wrapper preserved as label on upper cover, text in original printed wrappers (minor rubbing to spine).
FIRST EDITION of Ångström's detailed measurements of more than 1000 spectral lines. The plates are in effect a map of the solar spectrum, and shows the radiation of the solar spectrum range from 0.8 micron to 0.4 micron and red to purple. It identifies the particular lines of manganese, aluminium and titanium. The unit of length that bears his name is one millionth of a millimetre. Some copies have a further 2 plates showing the ultraviolet spectrum, but the Norman, Gedeon and Green copies - like the present copy - did not have these. Norman 56.
