چکیده انگلیسی
Knowledge of the vapor pressures and the sublimation/vaporization enthalpies of a metalorganic precursor can be indispensable for optimizing a deposition process. Unfortunately, published measurements of those values are often referred to a unique temperature, and comparing such studies requires adjusting the data to a common temperature. We tested four methods to adjust the difference between the heat capacities of the gaseous and condensed phases to the reference temperature 298.15â¯K. The tests used published data for the well-studied compound, ferrocene, as well as new data for the vapor pressure measured by the transpiration method in the range from 361â¯K to 435â¯K. The agreement among the four methods suggests that they will be reliable for other metal containing complexes for which limited thermodynamic data are available.
