Abstract To investigate the chemical effect on muon capture process through a transfer reaction from muonic hydrogen atom, formation rate of carbon atoms is measured for benzene and cyclohexane molecules in liquid samples. The to molecule higher than that molecule. Such deviation has never been observed among those gas This may be because transfers occur excited states system, whereas all 1 s (...

Abstract The oxidation number and of transferred electrons are two paramount parameters in the study redox reactions. Their calculations both important challenging. organic carbons is used chemistry, biochemistry, applied chemistry. Combustion reaction a classical type reaction, which oxygen molecule (O 2 ) oxidizing agent. In this article, integration three sets relations explored by using met...

abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...

In the present work, the joint use of the potential energy, the reaction electronic flux profiles and NBO analysis along the intrinsic reaction coordinate within the framework of the reaction force analysis allows us to gain insights into the mechanism of the proton transfer process in amino acids. The reaction was studied in alanine and phenylalanine in the presence of a continuum and with add...

A new approach for the computation of probability distributions of molecule populations for coupled first-order chemical reactions is introduced. The approach is based on system theory, where the system states are type of molecules (molecule species) and the signals are probabilities. The transfer functions of the defined systems can be applied to both closed and open reaction systems. The use ...

In 1954, Vogt and Wannier (Phys. Rev. 95, 1190) predicted that the capture rate of a polarizable neutral atom or molecule by an ion should increase factor two compared to classical Langevin as collision energy approaches zero. This prediction has not been verified experimentally. The H$_2^+$ + H$_2$ reaction is ideally suited observe this effect, because small reduced mass makes quantum effects...
