Infra-red Absorption Spectra of Steroids

چکیده
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 steroids. A study has also been made of a synthetic estrogen? stilbestrol (4,4’-dihydroxy-a ,p-diethylstilbene).

Infra-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 کاملThe Absorption Spectra of Hemoglobin and Its Derivatives in the Visible and near Infra-red Regions
Since the pioneering investigations of Vierordt and of Hiifner and his group, numerous reports on the absorption spectra of hemoglobin and its derivatives have appeared in the literature. A detailed summary of these reports is to be found in Heilmeyer’s monograph (1). For the most part these investigations have been confined to the visible portion of the spectrum, although in a few cases the ob...
متن کامل3 Absorption spectra of Fe L - lines in Seyfert 1 galaxies
Absorption L-lines of iron ions are observed, in absorption, in spectra of Seyfert 1 galaxies by the new generation of X-ray satellites: Chandra (NASA) and XMM-Newton (ESA). Lines associated to Fe 23+ to Fe 17+ are well resolved. Whereas, those corresponding to Fe 16+ to Fe 6+ are unresolved. Forbidden transitions of the Fe 16+ to Fe 6+ ions were previously observed, for the same objects, in th...
متن کاملInfra Red and Ultra Violet Spectra of Some Divalent Transition Cupferrone Complexes
The IR and UV absorption spectra of the ammonium salt of cupferrone and manganese, cobalt, nickel, copper and zinc divalent cupferrate complexes are investigated. The IR absorption bands identified in the region 400-4000 cm '1 are given and assigned, especially those three related to M -0 vibrations. In the UV absorption spectrum of the cupferrone m etal complexes a characteristic shift in the ...
متن کاملInteraction of Guar and Xanthan Gums with Starch in the Gels Obtained from Normal, Waxy and High-amylose Corn Starches
The objectives of the present study were to analyze the chemical interactions between guar and xanthan gums and starches. Gels were obtained from normal (NCS), waxy (WCS) and high-amylose (HACS) corn starches containing gums. The gels were evaluated according to their pasting properties and infra-red absorption. The guar (GG) and xanthan (XG) gums affected the properties of the NCS paste more s...
