โฆ Synopsis
The intermolecular stretching vibration of hydrogen bonded complexes between phenol derivatives and tetramethylthiourea or dimethylthioformamide is observed in the range 113 -131 cm-'.
The corresponding force constants ko are computed using the Lippincott-Schroeder potential function and the matrix method of Wilson. The ko values are higher than these oreviously reported for the complexes of the same phenols with aliahatic amides. These results are in qualitative agreement with the theoretical predictions.
