The infrared spectra of PH 3 molecule were recorded on a Bruker IFS 120HR Fourier transform spectrometer from 4000 to 9500 cm Ϫ1 . The P-H stretching vibrational frequencies and intensities were derived from the experimental data. The Morse oscillator parameters D e and ␣ in the anharmonically coupled anharmonic oscillator local mode model were determined by the least-squares fitting with the observed vibrational band centers. The ab initio three-dimensional P-H stretching dipole moment surfaces were calculated by the density functional theory method. The dipole moment vectors were projected to three kinds of molecule-fixed reference systems. The corresponding dipole moment components were fitted to polynomial functions in terms of the P-H bond length displacements with the molecular symmetry taken into account. The absolute band intensities were obtained and then compared with the experimental data. The results showed that a proposed improved bond dipole model can predict the absolute band intensities within a factor of 2 for most of the observed transitions, indicating a reasonably good agreement.

“…Another serious problem that this time emerges from the side of unification is the so called "ad explanandum" problem (Halnonen and Hintikka 1999;Petkov 2015). Halonen and Hintikka (1999) have criticized explanatory unification because it typically presents the embedding of more specific explanations into more general ones, as a type of inferential derivation. Halonen and Hintikka have suggested that this derivation implies that the explananda are considered as deductively closed or static.…”

The Degrees of Understanding and the Inferential Component of Understanding

Current debates on the nature of explanatory understanding have converged on the idea that at least one of the core components of understanding is inferential. Philosophers have characterized the inferential dimension of understanding as consisting of several related cognitive abilities to grasp a given explanation and the nexus of complementing explanations to which it belongs. Whilst analyses of both the subjective epistemic abilities related to grasping and objective features of the inferential links within explanations have received much attention, both within theories of explanation and in the literature on understanding, the criteria for evaluating the specific structure and organization of explanatory clusters or nexuses has received much less attention. Nevertheless, two notable exceptions stand out-Khalifa's characterization of an explanatory nexus, and theories of explanatory unification. I take Khalifa's ideas, together with the basic criteria of successful explanatory unification, as my starting point. To both I make some corrections and additions, in order to arrive at a more robust notion of an explanatory nexus and ultimately show that its structural properties and the inter-explanatory relations it contains are relevant to the resulting understanding.The Degrees of Understanding and the Inferential Component of Understanding 747 Organon F 28 (4) 2021: 746-776 I propose to represent such nexuses as directed graph trees and show that some of their properties can be related to the degree of understanding that such nested explanatory structures can offer. I will further illustrate these ideas by a case study on an ecological theory of predation.
