Abstract
|
|
|
|
| Using variable-temperature infrared spectroscopy, the vapor phase complexation enthalpy for the van der Waals complex CH3F . BF3 has been determined to be -16.5(7) kJ mol(-1). This value is compared with literature values obtained for solutions in liquid argon and in liquid krypton. The complexation enthalpy was transformed by statistical thermodynamics into a complexation enthalpy of -19.8(14) kT mol(-1), and this value is compared with ab initio results in which the geometry of the complex is optimized at different levels between MP2/6-31++G(d,p) and MP2/aug-cc-PVQZ, using BSSE-conected potential energy surfaces.
