Conclusions

  1. 1.

    In phosphoryl compound + HCCl3 + CCl4 systems, hydrogen-bonding complexes form with chloroform with 1∶1 and 1 ∶ 2 compositions.

     
  2. 2.

    The enthalpy of formation of a hydrogen bond between a phosphoryl compound and HCCl3 has been evaluated, and it correlates linearly with the shift in the overtone in the range measured.

     
  3. 3.

    A linear correlation of -ΔH with the sum of the Taft constants of the substituents on the phosphorus has been found.
