Product molecule numbers and reaction rate fluctuations in elementary reactions

Intramolecular anodic olefin coupling reactions: use of the reaction rate to control substrate/product selectivity.

Multi-product exporters, variable markups and exchange rate fluctuations

In this paper we investigate how firms adjust markups across products in response to fluctuations in the real exchange rate. In a theoretical framework, we show that firms increase their markups and producer prices following a real depreciation and that this increase is greater for products with higher productivity, a consequence of local distribution costs. We estimate markups at the market-pr...

Rate Coefficients and Product Ion Distributions for Reactions

ion provides the dominant channel of reaction (6): C0 2 • C02+ + CH4 CH4+ 42 C0 2 , (6a) CH4+ + C02 -> (C0 2 -CH 4 +)* , (21) (C02 • CH4+)* -> CO2H+ + CH3 , (22) (C02 • CH4+)* + C02 -> C02 • CH4+ + C 0 2 , (23) C02H+ + 2 C02 -> (C02)2H+ + C0 2 . (24) In this mechanism the formation of CO2 • CH4 + occurs by collisional stabilization of the intermediate reaction complex (C02 • CH4)* rather than v...

Apparent rate constant for diffusion-controlled three-molecule reactions.

We present simple explicit estimates for the apparent reaction rate constant for threemolecular reactions. For small concentrations and d > 1, it depends only on the diffusion coefficients and sizes of the particles. For small concentrations and d ≤ 1, it is also time – dependent. For large concentrations, it gains the dependence on concentrations. Typeset using REVTEX 1

Metal-molecule interface fluctuations.

We have created self-assembled circular chains of C60 laterally bound to a layer of Ag atoms as a model system for characterizing fluctuations at a metal-molecule interface. STM measurements show that the Ag and C60 sides of the interface fluctuate independently, with frequency-dependent amplitudes of magnitude 0.1 nm at approximately 1 Hz for the Ag edge and approximately 0.01 Hz for the C60 r...
