Some empirical correlations between the thermodynamic properties of hydrogen cyanide, water and acetylene molecules and their infrared spectra [PDF]

open access: yesTrakia Journal of Sciences, 2018
A new method for calculating vibrational modes in the infrared region of the spectrum is proposed. The method is based on the thermodynamic parameters of the molecules- standard molar Gibbs free energy change of molecular formation ΔGf0 (kJ/mol ...

Standard enthalpies of formation of selected Ru2YZ Heusler compounds [PDF]

open access: yesJournal of Alloys and Compounds, 2015
Abstract The standard enthalpies of formation of selected ternary Ru-based Heusler compounds Ru2YZ (Y = Fe, Hf, Mn, Ti, V; Z = Al, Ga, In, Si, Ge, Sn) were measured using high temperature direct reaction calorimetry. The measured enthalpies of formation (in kJ/mole of atoms) of the Heusler compounds are, Ru2FeGe (−19.7 ± 3.3); Ru2HfSn (−24.9 ± 3.6 ...
