The thermophysical properties of three globular molecules
(Elsevier, 1961-01)
The low temperature heat capacities of adamantane, hexamethylenetetramine and triethylenediamine have been determined from 5 to 350[deg]K by adiabatic calorimetry. A transition at 208.6[deg]K involving an entropy increment ...
Benzene Vibrational Exciton Spectrum
(The American Institute of Physics, 1967-11-01)
A critical discussion of the infrared polarization assignments of Zwerdling and Halford, in view of the now accepted benzene crystal structure, leads to acceptance of their results, though with somewhat reduced credibility. ...
Molecular Freedom of the Ammonium Ion. Heat Capacity and Thermodynamic Properties of Ammonium Perchlorate from 5°–350°K
(The American Institute of Physics, 1969-06-15)
The heat capacity of NH4ClO4 has been determined by adiabatic calorimetry from 5°–350°K and found to be of simple sigmate character without thermal anomalies. The heat capacity (Cp)(Cp), entropy (S°)(S°), enthalpy function ...
Thermal Properties Based upon Heat Capacity and Decomposition Pressure of Tetramethylammonium Hydrogen Dichloride. Nature of the Hydrogen Bond in the [Cl☒H☒Cl]— Ion
(The American Institute of Physics, 1962-05-15)
The heat capacity of tetramethylammonium hydrogen dichloride was determined from 5° to 350°K by adiabatic calorimetry and the derived thermodynamic properties were calculated. No thermal anomalies were found. Molal values ...
