Role of hydrogen bonding studied by the FTIR spectroscopy of the matrix-isolated molecular complexes, dimer of H/sub 2/O, H/sub 2/O. CO/sub 2/, H/sub 2/O. CO, and H/sub 2/O/sub 2/. nCO in solid O/sub 2/ at 12-17 K
Molecular complexes of H/sub 2/O, H/sub 2/O/sub 2/, CO, and CO/sub 2/ in solid O/sub 2/ have been prepared by a conventional matrix deposition method using an appropriate gas mixture. FTIR spectra and vibrational assignments of matrix-isolated H/sub 2/O dimer and trimer, H/sub 2/O.CO/sub 2/, H/sub 2/O.CO, H/sub 2/O.H/sub 2/O/sub 2/, and H/sub 2/O/sub 2/.nCO in solid O/sub 2/ are presented. Hydrogen bonds of the type O...H-O involving H/sub x/O/sub z/ species and C...H-O involving H/sub x/O/sub z/.nCO species are found except for H/sub 2/O.CO/sub 2/. In the H/sub 2/O.H/sub 2/O/sub 2/ complex, H/sub 2/O/sub 2/ is an electron acceptor (acid) and H/sub 2/O is an electron donar (base). The frequency shift of the O-H stretch in the electron acceptor molecule of the complex increases in order of H/sub 2/O.CO, H/sup 2/O/sub 2/.CO, (H/sub 2/O)/sub 2/, and H/sub 2/O.H/sub 2/O/sub 2/. 41 references, 6 figures, 6 tables.
