Infra-red Absorption Spectra of Steroids
In this paper, the infra-red absorption spectra of a number of crystalline natural estrogens are presented and considered in relation to chemical structure. As a group, the natural estrogens are distinguished chemically from other steroids by the benzenoid structure of Ring A, which gives rise to certain infra-red absorption bands by which their spectra may be differentiated from those of other...
متن کاملInfra-red Absorption Spectra of Pyrylium Salts
The infra-red absorption spectra of the unsubstituted pyrylium cation and of 25 di-, tri-, tetraand per&-substituted pyrylium salts (mostly perchlorates) with alkyl and/or phenyl groups are described. Assignments of IR bands are made in correlation with the spectrum of pyridine, and the variation of band position and intensity depending on substitution is discussed. Implications for the assignm...
متن کاملInfra-Red Absorption Spectra of Chlorophylls and Derivatives.
We have measured the infra-red absorption spectra of chlorophyll and some of its derivatives in order to obtain information useful for eventual understanding of reversible transformations of this pigment. Such transformations are (a) Moliseh phase test, (b) bleaching by FeCl3, and (c) photochemical reduction by ascorbic acid-"Krasnovsky reaction" (10, 13, 16). Only in the case of the phase test...
متن کاملMinimizing Strong Telluric Absorption in Near Infra-red Stellar Spectra
We have obtained high resolution spectra (R ∼ 25000) of an A star over varying airmass to determine the effectiveness of telluric removal in the limit of high signal to noise. The near infra-red line He I at 2.058μm, which is a sensitive indicator of physical conditions in massive stars, supergiants, H II regions and YSOs, resides among pressure broadened telluric absorption from CO2 and water ...
متن کاملHomogentisic Acid Oxidase*
In the course of a study of the properties of the homogentisic acid oxidase of rat liver the activity of other animal tissues has been briefly examined. The enzyme has been reported to occur in beef and hog (I), guinea pig (2), and rabbit (3) livers and in a strain of Pseudomonas (4). The experiments reported here show that the enzyme is also present in pigeon liver and in guinea pig, rabbit, p...
