The Chemistry of Plant Life It is a substance giving a banded absorption spectrum, and which, mixed with other pigments, imparts an abnormally browner tint. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 1 "Edwardes" to "Ehrenbreitstein" Its salts are reddish violet in colour, and give a characteristic absorption spectrum. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 4 "Diameter" to "Dinarchus" Mention may be made of the absorption spectrum of benzene. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 1 "Châtelet" to "Chicago" Engelmann showed, for instance, that these red-purple bacteria collect in the ultra-red, and to a less extent in the orange and green, in bands which agree with the absorption spectrum of the extracted colouring matter. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" All the almandine garnets which I have examined, and nearly all the jargoons, show these characteristic absorption spectra. Scientific American Supplement, No. 1082, September 26, 1896 An absorption spectrum is in each case obtained, but the one from the solution is the purer, for it does not contain the mixed white light reflected from the surfaces of coloured objects. The Chemistry of Hat Manufacturing Lectures Delivered Before the Hat Manufacturers' Association It is four times lighter than water, it does not present any absorption spectrum, and its specific heat is the greatest known. The New Physics and Its Evolution Examination of the absorption spectra of coloured compounds shows that certain groupings displace the absorption bands in one direction, and other groupings in the other. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 1 "Châtelet" to "Chicago" Neelson found that the pigment of B. cyanogenus gives a band in the yellow and strong lines at E and F in the solar spectrum—an absorption spectrum almost identical with that of triphenyl-rosaniline. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" We may thus observe three principal absorption spectra.
