“…The EI mass spectrum has been reported for hydroxyl radical, 33 water, 33 and hydrogen peroxide. 34 As expected, the dominant ions in the 70 eV EI mass spectrum of hydroxyl radical are OH + , m/z 17, while for water it is H 2 O + , m/z 18. For hydrogen peroxide, 34 there is little fragmentation following 70 eV EI, and the H 2 O 2 + parent peak, m/z 34, is 5 times more intense 34 than the OH + fragmentation ion.…”

We have studied the oxidation of self-assembled monolayers (SAMs) of alkanes and alkenes with a thermal beam of OH radicals. The target films were produced by bonding alkane thiols and alkene thiols to a gold surface and the SAMs are mounted in a vacuum chamber at a base pressure of 10-9 Torr. Hydroxyl radicals were produced by a corona discharge in an Ar/H2O2/water mixture. The resultant molecular beam was scanned by an electrostatic hexapole and the OH radicals [4 (+/- 1) x 1011 OH radicals cm-2 sec-1] were focused onto the target SAM. All of the hydroxyl radicals impinging on the SAM surface are rotationally (J' '

“…The discrepancy between the values for the appearance potential (Table II) obtained by Robertson (186) and by Foner and Hudson (57) was ascribed by the latter to interference from decomposition products mentioned above which was eliminated in their work (57). Similar interference from decomposition products had been encountered by others (114, 130). Muschlitz and Bailey (160) have studied the mass spectra of water vapor and mixtures of water and hydrogen peroxide vapors.…”

“…In order to translate these data into the actual state of the molecule, we assume that the energy of the highest filled orbital is equal t o the one experimentally lr~lowil ioilizatioll potential, 11.26 ev (20). Addition of this ad hoc constant, 4.83 (= 11.26-6.43), yields the values shown in Fig.…”

The electronic structure of the hydrogen peroxide lnolecule i11 three differe~~t configurations, namely the cis, the trans, and the non-planar or skew forms, were calculated according t o the LCAO-MO-SCF approxin~ation. All the electrons were considered except those of the K-shell of the osygerl atoms. The orbitals of these atonls are essentially of the sp3 hybrid type. It was shown that the skew form of the molecule with an azimuthal angle % of about 120" is the most stable, due mainly to conjugation of the a5 and 0 6 orbitals of the oxygen atoms with the other n~olecular orbitals. On the contrary, in the cis and trans forms these two orbitals are non-bonding. Because of the approximate nature of the treatment, especially as regards the screening effect of the I<-electrons, the calculated orbital energies are definitely too large. However, the heights foulld for the cis and the trans barriers are in a reasonable mutual ratio. N~rrnerical values were also obtained for the ionization potentials and the dipole moment of the skew model; the latter result, 2.05 D, agrees well with the experimental data.
