Magnetically modulated optical nanoprobes
(The American Institute of Physics, 2003-02-17)
We have developed magnetically modulated optical nanoprobes (MagMOONs) to magnetically modulate the signal from fluorescent probes and thus separate it from autofluorescence, electronic offsets, and other background signals. ...
The microwave spectrum, ab initio analysis, and structure of the fluorobenzene–hydrogen chloride complex
(The American Institute of Physics, 2003-05-22)
The fluorobenzene–hydrogen chloride π-hydrogen-bonded complex has been studied by high resolution microwave spectroscopy and ab initio calculations. Rotational spectra of the C6H5F–H35Cl,C6H5F–H35Cl, C6H5F–H37Cl,C6H5F–H37Cl, ...
Fractal chemical kinetics: Reacting random walkers
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1984-09)
Computer simulations on binary reactions of random walkers ( A + A → A ) on fractal spaces bear out a recent conjecture: ( ρ −1 − ρ 0 −1 ) ∞ t f , where ρ is the instantaneous walker density and ρ 0 the initial one, and f ...
Nonclassical crossovers in binary reactions in one-dimensional systems
(Elsevier, 1994-01)
We examine the crossover behavior for the A + A --> O and A + B --> O reactions, which are highly nonclassical for a random initial distribution of reactants. We find that both reactions quickly depart from the ...
Assignments of the n[pi]* singlet states of p-benzoquinone
(Elsevier, 1974-03-30)
The vapor phase fluorescence spectra of p-benzoquinone-h4 and d4 are reported and discussed in relation to the assignment of the low lying singlet states. The low temperature, polarized single crystal electronic absorption ...
Rate processes on fractals: Theory, simulations, and experiments
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1986-01)
Heterogeneous kinetics are shown to differ drastically from homogeneous kinetics. For the elementary reaction A + A → products we show that the diffusion-limited reaction rate is proportional to t − h[A] 2 or to [A] x , ...
The vibrational relaxation of I2I2 (X 1Σg+)(X1Σg+) in mesitylene
(The American Institute of Physics, 1998-03-22)
Transient absorption measurements between 400 nm and 570 nm are used to extract information on the vibrational relaxation of iodine in the complexing solvent mesitylene. The well characterized nature of the I2I2-arene ...
Dynamics of energy transport in ternary molecular solids. I. Naphthalene steady state fluorescence
(Elsevier, 1981-05-01)
Energy transport experiments were conducted at liquid helium temperatures on ternary single crystals (host/guest/ supertrap, i.e. C10H8/C10D8/betamethylnaphthalene-d10) at guest concentrations of 50--99% and very low (about ...
Percolation and cluster distribution. III. Algorithms for the site-bond problem
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1979-11)
Algorithms for estimating the percolation probabilities and cluster size distribution are given in the framework of a Monte Carlo simulation for disordered lattices for the generalized site-bond problem. The site-bond ...
