    Electronegativity and its Multiple Faces: Persistence and Measurement.Klaus Ruthenberg & Juan Camilo Martínez González - 2017 - Foundations of Chemistry 19 (1):61-75.
    Electronegativity is a quantified, typical chemical concept, which correlates the ability of chemical species to attract electrons during their contact with other species with measurable quantities such as dissociation energies, dipole moments, ionic radii, ionization potentials, electron affinities and spectroscopic data. It is applied to the description and explanation of chemical polarity, reaction mechanisms, other concepts such as acidity and oxidation, the estimation of types of chemical compounds and periodicity. Although this concept is very successful and widely used, and in (...)

    Isomerism and Decoherence.Sebastian Fortin, Olimpia Lombardi & Juan Camilo Martínez González - 2016 - Foundations of Chemistry 18 (3):225-240.
    In the present paper we address the problem of optical isomerism embodied in the socalled “Hund’s paradox”, which points to the difficulty to account for chirality by means of quantum mechanics. In particular, we explain the answer to the problem proposed by the theory of decoherence. The purpose of this article is to challenge this answer on the basis of a conceptual analysis of the phenomenon of decoherence, that reveals the limitations of the theory of decoherence to solve the difficulties (...)

    Why Molecular Structure Cannot Be Strictly Reduced to Quantum Mechanics.Juan Camilo Martínez González, Sebastian Fortin & Olimpia Lombardi - 2019 - Foundations of Chemistry 21 (1):31-45.
    Perhaps the hottest topic in the philosophy of chemistry is that of the relationship between chemistry and physics. The problem finds one of its main manifestations in the debate about the nature of molecular structure, given by the spatial arrangement of the nuclei in a molecule. The traditional strategy to address the problem is to consider chemical cases that challenge the definition of molecular structure in quantum–mechanical terms. Instead of taking that top-down strategy, in this paper we face the problem (...)

    Entre mecánica cuántica y estructuras químicas: ¿a qué refiere la química cuántica?Olimpia Lombardi & Juan Camilo Martínez González - 2012 - Scientiae Studia 10 (4):649-670.
    El propósito del presente trabajo consiste en abordar la pregunta por la ontología de la química cuántica. Para ello nos concentraremos en el concepto de enlace químico desde la perspectiva de los dos enfoques a través de los cuales la ecuación de Schrödinger se aplica a los sistemas químicos moleculares: la teoría del enlace de valencia (EV) y la teoría del orbital molecular (OM). Sobre la base de la presentación de ambos enfoques y su comparación, señalaremos que, a pesar de (...)
