摘要:
Reported Values of Structural parameters, vibrational fundamentals, and potential energy functions for internal rotation of n‐butane and isobutane are reviewed. The selected values were used to calculate the thermodynamic properties (C°p, S°, (H°‐H°0)/T) in the temperature range of O to model. Contributions of internal rotation were evaluated by the direct sum of terms containing energy levels which were calculated with a one‐dimensional potential model. For internal rotation about the central C‐C bond in n‐butane, energy levels were approximated by two procedures. A inique potential function was assumed for each methyl rotor of n‐butane or of iso

摘要:
Data on the electrical conductance, density, viscosity, and surface tension chloride mixtures have been systematically collected and evaluated. results are given in 124 binary mixtures over a range of compositions and temperatures. Values of the above properties for the single salts have been updated in accord with previously advanced recommendations.
