I present an overview of some common carboxylic acids, their formulas, uses and location.

Los Isómeros son substancias distintas que tienen la misma fórmula molecular y difieren en su estructura

Lignin degradation by peroxidase or an extracellular crude ligninase in the presence of thiourea is enhanced. Veratryl alcohol, exhibits the same behaviour in both cases. Thiourea is proposed as an additive in biopulping

Several organic radical transformations in aqueous media using organometallic chemistry are presented. Group XIV-elements, such as Si and Ge, and Sn-centered radicals make use of novel methodologies in water which employ ...

Matter is build up by atoms and these of subatomics particles: protons, neutrons and electrons. The atoms form bonds with their valence electrons. In organic compounds, the chemical bond is covalent, and because ...

By means of an iterative consistency method it has been determined a complete potential field for the urea molecule. The force constants set which interpretates well the vibrational spectra of urea and its deutero derivatives ...

The IR and Raman spectra of solid diamminemercury(II) chloride with 14N/15N and H/D isotopic substitution have been measured. The spectra have been interpreted assuming D3d symmetry for the [Hg(NH3)2]2+ cations which have ...

Coriolis coupling constants and the inertia defect for cis- and trans-1,2-dichloroethylene have been calculated, using force constants obtained by the iterative consistency method. The results obtained are compared with ...
