The birth, raise, development and fortunes of a fundamental theory in thermodynamics, the axiomatic thermodynamics, a creation of Constantin Carathéodory, is thoroughly presented together with a summary of Carathéodory’s biography. Axiomatic thermodynamics is centered around some interesting properties of Pfaffian differential equations, which are here(More)

A molecular connectivity model for the calculation of the relaxation times of amino acids and cyclic dipeptides is presented. A power type regression shows the best fit between experimental and calculated data. The simple molecular connectivity index and the simple sum-delta index are the most appropriate indexes in describing the relaxation times of the(More)
The proton magnetic resonance (PMR) spectrum of acetyl-proline amide in D2O solution has been analysed by computer simulation. The spectra of the cis and the trans isomers have been separated and their PMR parameters (chemical shift and coupling constants) are given. Vicinal coupling constants of the pyrrolidine ring are interpreted by means of a Karplus(More)
The internal formal similarity of different higher-level molecular connectivity descriptors, also known as molecular connectivity terms, which can be derived by a trial-and-error procedure from a medium-sized set of eight molecular connectivity indices or a subset of it has been thoroughly analyzed. These molecular connectivity terms are interesting(More)
Eight different properties of three classes of compounds, metal halides, halomethanes, and chlorofluorocarbons, have been modeled with the aim to check the validity of the odd complete graph conjecture suggested for encoding the contribution of the inner-core electrons to the molecular connectivity indices. Modeling using this conjecture is compared with(More)
