PHOTOFRAGMENTATION OF GASEOUS HCOOH AT THE O 1s EDGE
نویسندگان
چکیده
Time of flight mass spectrometry with multi-ion coincidence detection has been used to investigate ionic photofragmentation of formic acid following O 1s excitation and ionization. Multi-ion coincidence spectra (PEPICO and PEPIPICO), branching ratios (BR) and partial ion yields (PIY) are reported. The multi-ion coincidence detection is used to identify the dissociation channels following O 1s excitation and to explore the dynamics of fragmentation. The fragmentation mechanisms are suggested using twoand three-body decay approximation.

Computational Study of the Mechanism, Reaction Rate and Thermochemistry of Atmospheric Oxidation of Methylamine with Singlet Oxygen
The reaction of CH₃NH₂ with O₂ on the singlet potential energy surfaces (PES) was carried out using the B3LYP, CCSD(T) and G3B3 theoretical approaches along with 6-311++G(3df,3pd) basis set. The suggested mechanism for the title reaction consists of one pre-reactive complex. From the pre-reactive complex, nine types of products, CH2NH+H2O2, CH3NH+OOH,...
متن کاملNear edge X-ray absorption mass spectrometry of gas phase proteins: the influence of protein size.
Multiply protonated peptides and proteins in the gas phase can respond to near edge X-ray absorption in three different ways: (i) non dissociative ionization and ionization accompanied by loss of small neutrals, both known to dominate for proteins with masses in the 10 kDa range. (ii) Formation of immonium ions, dominating for peptides in the 1 kDa range. (iii) Backbone scission leading to sequ...
متن کاملX-ray absorption near edge structures of DNA or its components around the oxygen K-shell edge.
The initial process of radiation damage in DNA was investigated by measuring the X-ray absorption near edge structures (XANES) within the energy region around the oxygen K-shell absorption edge for DNA, cytosine and 2-deoxy-d-ribose. Irradiation and XANES experiments were performed with the BL23SU soft X-ray beamline, using synchrotron radiation from the 8 GeV electron storage ring at SPring-8....

The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
متن کاملCarbon K edge structures of molecular crystals from first-principles: A comparison between phenanthrene and anthracene
By means of ab-initio calculations on the basis of the FPLAPW method, we compared the energy loss near edge structure (ELNES) of carbon K edges in crystalline phenanthrene and its isomer, anthracene. In these two organic compounds, different non-equivalent carbon atoms can result in distinct K edge spectra due to the different carbon-carbon bond lengths, as a characteristic behavior of the mole...
