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
A theory for vibrational predissociation of hydrogen-bonded OH...0 complexes via OH stretch-00 stretch energy transfer is constructed, motivated by a recent experiment on vibrational predissociation of hydrogen-bonded ethanol dimer in solution. The theory employs a vibrationally adiabatic perspectiv
