Study of Spectroscopy and Thermodynamic Properties for Germanium Tetrafluoride GeF4 Molecular and Study of Potential Energy Curve for Bond (Ge-F)

Engineering and Technology Journal, 2011, Volume 29, Issue 3, Pages 117-124

In This research Complete study Spectroscopic and Thermodynamic
properties for molecule GeF4 . This included calculation of potential energy
curve . from this curve total energy of molecule at equilibrium distance
calculated , for bond (Ge - F) the degenerated of (Ge -F ) bond was (2.99 ev)
instate of that the vibration modes of GeF4 and frequency in IR spectra region
because variable of dipole moment for molecule. Also we calculated
Thermodynamic properties for GeF4 such as Heat of formation , Enthalpy , Heat
of Capacity and Entropy Were (-290.231 kcal/mol , 4198.48kcal/mol , 19.61
kcal /k/mol , 82.25 kcal /k /mol,) respectively all at room temperature and one
atmosphere ( 298 k , 1 atm.) , and we calculated this properties at various
temperature from ( 100 – 3000 ) K . The calculated results are in a good
agreement with experimental results
