Entropies and Heat Capacities of Gaseous Selenium Molecules
The presumably cyclic molecules Ses, Se6 and Se; are the main constituents of saturated selenium vapor at temperatures up to 400 °C as well as of the vapor above freely subliming trigonal selenium, and cyclic Seg molecules can be prepared as various crystalline modifications [1], Small selenium rings are also discussed as constituents of liquid and amorphous selenium obtained by quenching the l...
متن کاملTemperature Dependence of Rutile (TiO2) and Geikielite (MgTiO3) Structures Determined Using Neutron Powder Diffraction
The temperature dependences of the structures of rutile and geikielite are reported up to ~1200C. While the thermal expansion of the unit cell edges for our rutile agree with published data the (Ti-O) bond expansions show significant differences with the longer (T-O) showing a larger thermal expansion coefficient (19.3 x 10 /degree) than the shorter bond (2.6 x 10 /degree). High-temperature cry...
متن کاملThermodynamics of liquids: standard molar entropies and heat capacities of common solvents from 2PT molecular dynamics.
We validate here the Two-Phase Thermodynamics (2PT) method for calculating the standard molar entropies and heat capacities of common liquids. In 2PT, the thermodynamics of the system is related to the total density of states (DoS), obtained from the Fourier Transform of the velocity autocorrelation function. For liquids this DoS is partitioned into a diffusional component modeled as diffusion ...
