Comment: phonon spectrum of molecular crystals from exciton sidebands
(Elsevier, 1974-11-01)
Phonon sidebands of excitons in molecular crystals with negligibly small excitation exchange interactions, including isotopic guest systems, are not, in general, expected to be predominantly weighted by translational modes ...
The numbers of chiral and achiral alkanes and monosubstituted alkanes
(Elsevier, 1976)
Whereas the theory for the enumeration of the optical isomers of the lakyl radicals and the alkanes has long been understood, this is not the case for the corresponding archiral isomers. We present for the first time ...
Heat capacity and thermodynamic properties of diamantane from 5 to 540 K
(Elsevier, 1978-10)
The heat capacity of diamantane, C14H20, has been measured by adiabatic calorimetry from 5 to 350 K. The heat capacity is generally sigmate except for a gradual thermal anomaly with a maximum at 35.7 K and an apparent ...
Low-temperature calorimetry — quo vadis?
(Kluwer Academic Publishers; Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest ; Springer Science+Business Media, 1978-10)
Experimental progress in adiabatic, cryogenic calorimetry is tersely reviewed and contrasted with other techniques for heat capacity determinations in this temperature region—including DSC. Trends and prognostications of ...
Cadmium and arsenite binding by N-dihydrolipoyl-aminoethoxydextran: A model study of enzyme dithiol criteria
(Elsevier, 1973)
We have observed the interaction of Cd2+, Zn2+, and AsO22- with a dithiol-substituted polymer (N-dihydrolipoyl aminoethoxy dextran). Cadmium binding results in an intense uv difference spectrum ([lambda]max = 240 nm). ...
The two-iron ferredoxins in spinach, parsley, pig adrenal cortex, Azotobacter vinelandii, and Clostridium pasteurianum: Studies by magnetic field Mossbauer spectroscopy
(Elsevier, 1971-11-02)
The two-iron ferredoxins from spinach, parsley, Azotobacter vinelandii, Clostridium pasteurianum and the pig adrenal cortex were investigated by Mossbauer spectroscopy at temperatures from 4 to 256[deg]K and in magnetic ...
Purification and comparison of several catalytic parameters of the [gamma]-glutamyltranspeptidase of rat mammary adenocarcinoma (13762) and of normal rat mammary gland
(Elsevier, 1979-06-06)
A method for the purification of a membrane-bound glycoprotein, [gamma]-glutamyltranspeptidase (([gamma]-glutamyl)-peptide:amino-acid [gamma]-glutamyltransferase, EC 2.3.2.2), from a transplantable rat mammary tumor (13762 ...
