Electronic structure of arsabenzene: Microwave spectrum, dipole moment, and nuclear quadrupole coupling constants
(Elsevier, 1975-09)
The microwave spectrum of arsabenzene was analyzed; a dipole transitions were observed. The following rotational constants were obtained; A = 4871.03 +/- 0.18 MHz, B = 2295.87 +/- 0.01 MHz, C = 1560.10 +/- 0.01 MHz. The ...
Methanol: Heat Capacity, Enthalpies of Transition and Melting, and Thermodynamic Properties from 5–300°K
(The American Institute of Physics, 1971-02-15)
Thermal properties of methanol were studied by adiabatic calorimetry. The first‐order nature of the phase transition at 157.4°K with an entropy increment of 0.97 cal mole−1⋅°K−1 was confirmed. The heat capacity of the ...
Isolation, characterization and partial sequencing of cystine and thiol peptides of pig heart lipoamide dehydrogenase
(Elsevier, 1974-11-25)
Pig heart lipoamide dehydrogenase (EC 1.6.4.3) contains ten half-cystines (as cysteic acid) per mole of enzyme bound FAD. Two of these are linked in an intrachain cystine which acts in concert with the flavin during ...
Manganese Disulfide (Hauerite) and Manganese Ditelluride. Thermal Properties from 5 to 350°K and Antiferromagnetic Transitions
(The American Institute of Physics, 1970-04-01)
The heat capacities of manganese disulfide and manganese ditelluride were determined by adiabatic calorimetry in the range 5–350°K. Lambda‐type transitions are present in both compounds with maxima at 47.93°K for MnS2 and ...
Molecular structure of n-butane: calculation of vibrational shrinkages and an electron diffraction re-investigation
(Elsevier, 1977-05)
A normal coordinate analysis was carried out based on the force field of Schachtschneider and Snyder in order to calculate all amplitudes of vibration and shrinkage corrections for n-butane. The results are tabulated to ...
Coherent potential theory for interacting bands: Phonons and excitons in substitutionally disordered molecular crystals
(The American Institute of Physics, 1973-03-15)
A coherent potential approximation (CPA) theory for disordered molecular solids with interacting bands is reported here. This theory has a wide range of applications. Various examples of interacting bands can be cited, ...
Reconstitution of cyanobacterial photophosphorylation by a latent Ca+2-ATPase
(Elsevier, 1979-10-12)
Photosynthetic membranes derived from sonic extracts of the cyanobacterium contain a latent Ca+2-ATPase which is activated by exposure to trypsin. When sonic membranes are washed with ethylenediaminetetraacetic acid, the ...
