Bildung von gasförmigem POCl Massenspektrometrische und Matrix-IR-Untersuchungen

Formation of Gaseous POCl Mass-spectrometric and Matrix-IR Investigations The formation of gaseous POCl by reaction of POCl₃ with silver at about 1100 K has been shown by mass spectrometric and IR matrix investigations. The heat of formation and entropie has been calculated at ΔH₂₉₈₂₉₈ (POCl) = ?250.7 kJ/Mol, S₂₉₈ (POCl) = 274.5 J/K · Mol. An approximate force constant calculation is presented as the three possible vibrational frequencies (1257.7 cm^?1, 489.4 cm^?1, 308.0 cm^?1) and some isotopic shifts (¹⁶O/¹⁸O; ³⁵Cl/³⁷Cl) are observed in an Ar-matrix.
