Bimolecular reaction A + B --> 0 at steady state on fractals: Anomalous rate law and reactant self-organization
(Elsevier, 1990-10-01)
This paper is a theoretical investigation of the diffusion limited reaction A + B --> 0 at steady state and on fractal structures. We propose an extension of a scheme previously applied to Euclidean spaces, using the ...
Fractal exciton fusion: Simulations on long-range percolation clusters
(Elsevier, 1984-12)
Computer simulations of exciton fusion on percolating clusters were performed for interaction distances N=2, 3, and 4. The data yield slopes less than those expected from superuniversality (f=2/3) at interaction distances ...
The thermodynamics of the divalent metal fluorides. II. Heat capacity of the fast ion conductor BaSnF 4 from 7 to 345 K
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1988-11)
The heat capacity of the fast ion conductor BaSnF 4 was measured over the temperature range 7< T <345 K using adiabatic calorimetry. Our results show that a phase transition is not present. However, an anomalous rise in ...
Electron diffraction studies of hot molecules. II. ‘‘Anharmonic shrinkage effects’’ in SF6, CF4, and SiF4
(The American Institute of Physics, 1982-08-15)
Least squares refinements of diffraction intensities for SF6, CF4, and SiF4 yielded nonbonded internuclear distances that lagged increasingly behind values expected from the bond lengths, the higher the temperature. The ...
Effect of zero field splitting interactions on the paramagnetic relaxation enhancement of nuclear spin relaxation rates in solution
(The American Institute of Physics, 1993-01-15)
The enhancement of nuclear spin relaxation rate R1m that is produced by paramagnetic metal ions in solution (the NMR‐PRE) has been investigated for electron spin systems with S=1 using recently developed relaxation theory ...
Analysis of the ESR spectrum of manganese (II) in the layered compound Cd2P2Se6
(Elsevier, 1986-07-01)
The Q-band and X-band ESR spectra of Mn2+ in the layered compound Cd2P2Se6 are reported. The Mn2+ is in a trigonal environment coordinated to six selenium atoms. The parameters of the spin hamiltonian have been determined ...
The ground state fundamentals of p-benzoquinone and p-benzoquinone-d4
(Elsevier, 1974-03-30)
The solid state infrared and Raman spectra of p-benzoquinone and several isotopic derivatives are reported and compared with the results of previous solution and vapor phase studies and with the results of previously ...
A Closed General Solution of the Probability Distribution Function for Three‐Dimensional Random Walk Processes
(The American Institute of Physics, 1961-02)
A closed general solution of the probability distribution function for three‐dimensional random walk processes is derived. In addition: (1) For the particular case of equal‐length displacements, the exact solution is ...
ESR studies of inter- and intra-lamellar cation exchange processes in Cd2P2S6
(Elsevier, 1990)
The transition metal chalcogenides, M2P2S6 (M = divalent transition metal cation), are lamellar materials that undergo an unusual cation exchange process when their crystals are placed in contact with a solution of a ...
Correlated hopping model for singlet exciton transport in lightly dohttp://www.sciencedirect.com/science/article/B6TFM-44DTGD2-KF/2/d498b4c6ab57aaaa33fd7a30ddc18badped naphthalene crystals
(Elsevier, 1980-09-15)
A formalism of correlated lattice random walk is applied to the singlet exciton transport in naphthalene. Fluorescence experiments on excitation migration in naphthalene crystals (C10H8 and C10D8), lightly doped chemically ...
