Matix isolation infrared spectroscopy applied to the ethylene oxide/H(D)I system trapped in solid Ar and N2 allows identification of several kinds of hydrogen-bonded complexes: a 1:1 species which exists under different structures and larger aggregates giving rise to proton transfer with formation of ionic species of the type + or (IHI)- characterized by quasi-symmetrical single-minimum potential functions for the proton (proton sharing).The interconversion between the hydrogen-bonded (C) and the non-hydrogen-bonded (U) form of the 1:1 complex is seen to depend on two parameters: temperature and infrared irradiation.Kinetic measurements of the disappearance (or appearance) of C have shown that the C->U conversion is mainly induced by IR radiations in the range 1500-2300 cm-1, corresponding to the excitation of νs (HI stretching mode), while the CU conversion rate with DI suggests a barrier greater than 1500 cm1- for this photoprocess.
