Infrared Absorption Spectra of Steroids (an Atlas)
comments (p. 82), "Apr's de publications initiales optimistes, ont succede des rapports negatifs." In the introduction, it becomes clear that French laboratory methods are much like ours. The Lee-White method and the Quick test are standard procedures. On the other hand, the Continental workers seem to place more emphasis than we do on the in vitro heparin tolerance. Later portions of the book ...
متن کاملInfrared Spectra of High Polymers . II . Polyethylene *
The infrared spectrum of polyethylene has been obtained between about 3000 cm-1 and 70 em-I, polarization measurements on oriented specimens having been obtained to about 350 em-l. Assignments of the fundamentals are made with the help of a group theory analysis. The assignment of the controversial CH. wagging mode is discussed in detail and especially in terms of new evidence from the spectra ...
متن کاملAcetylcholinesterase. II. Crystallization, absorption spectra, isoionic point.
The paramount role of acetylcholinesterase (ACh-esterase) in the control of electrical activity of excitable membranes of nerve and muscle cells appears well established.1-' In view of its vital function in nerve impulse conduction, the enzyme has been intensively studied since it was first extracted, in 1938, from electric tissue.4 In the early 1940's a several-hundredfold purification of this...
متن کاملInfrared absorption spectra of vinyl radicals isolated in solid Ne.
Irradiation of samples of solid Ne near 3.0 K containing ethene (C(2)H(4)) with vacuum ultraviolet radiation at 120 nm from synchrotron yielded new spectral lines at 3141.0, 2953.6, 2911.5, 1357.4, 677.1, 895.3, and 857.0 cm(-1). These features are assigned to alpha-CH stretching (nu(1)), CH(2) antisymmetric stretching (nu(2)), CH(2) symmetric stretching (nu(3)), CH(2)-bending (nu(5)), HCCH cis...
متن کاملNear-Infrared Absorption and Scattering Spectra of Tissues in Vivo
Tissue inhomogeneity is often neglected in the analysis of the spectral data collected in tissues. We have measured the absorption and reduced scattering spectra of the human forearm in the wavelength range 633-841 nm, and in the range of source-detector separations 0.7-3.3 cm. We found that the layered tissue structure due to the skin and adipose layers may have a significant effect not only o...
