“…6 The question has been raised, however, as to the transferability of the conclusions to thermal electron transfer processes, it being argued that the donor/acceptor orbitals might differ for the two processes. [7][8][9] Orbital models have played a crucial role in the interpretation of molecular electronic processes, including electronic spectroscopy, ionization and electron attachment, and charge transfer reactions. However, although the MO (moleular orbital) concept is helpful, orbitals do not have the same formal status as overall many-electron wave functions and the expectation values which they yield.…”

Both metal-to-ligand charge transfer (MLCT) and oxidation (ionization) processes have been investigated for (NH 3 ) 5 RuL 2+ complexes with L ) pyridine, pyrazine, and protonated pyrazine. Calculations were carried out using ZINDO-95. Self-consistent-field molecular orbitals (MO's) were obtained at the restricted HartreeFock level for the closed-shell ground state (t 2g ) 6 (NH 3 ) 5 RuL 2+ species. The MLCT wave functions and excitation energies were obtained by configuration interaction among all singlet configurations generated by single excitations from the highest 11 occupied MO's to the lowest 11 unoccupied MO's. We find that the Ru(II) d π orbital is the HOMO for all three complexes. The results provide clear indication that the relative energies for removing an electron from the three types of t 2g orbital depend on the effective distance that the electron is transferred. For relatively long-distance transfers (e.g., g5 Å as for intra-or intermolecular thermal or optical electron transfer to a weakly coupled Ru(III) site), the lowest energy process involves the d π orbital. In contrast, for the shorter range MLCT process, for which the electron interacts with the newly created hole to an extent determined by the relevant Coulomb and exchange integrals, the d π orbital participates in the highest energy of the three possible t 2g f L π* excitations. Accordingly, to the extent that the electronic coupling element for thermal or optical metal-to-metal electron transfer is enhanced by superexchange of the "electron" type involving the d π orbital, the relevant MLCT intermediate state is not the lowest energy but rather the highest energy one. It also follows that an electron from the same symmetry orbital (d π ) is transferred in both optical and thermal electron transfer processes involving the Ru(II)-Ru(III) couples considered.

“…More information could be obtained using Meyer's (2002) program for reconstruction of single layers of the reciprocal lattice from the full set of intensity data. The consecutive reciprocal lattice 1kL lines with L = 2, 2.66, 3, 4.66, 5 and 6 can be seen in the 1kl section of the reciprocal lattice (Fig.…”

“…3a and 3b) were obtained by recording the diffracted X-rays from the crystal rotated by 25 for about 4 min. They are presented in the colour palette used by the KUMA Diffraction program (Meyer, 2002). The full set of X-ray diffraction data was collected over the range 3±96 in 2 in ten runs with Á3 = 0.5 and longer than usual measuring time t = 30 s. Measured intensities were recorded in 1769 frames, each frame consisting of 512 Â 512 pixels.…”

“…The pressure at the filter face can be assumed to be the atmospheric pressure. 13 Based on the dew-point temperature and atmospheric pressure measured at Abbotsford Airport (approximately 17 km east-southeast of the study site), the 75 and 95% percentiles of the internal relative humidities were 8 and 11%, respectively, in TM50c, 13 and 16% in TM40c, and 26 and 34% in TM30c. Since these relative humidities were all less than 30% most of the time, the mass loss of particle-water likely was mostly similar in Table 1 all three monitors.…”

This study investigated the effect of equilibration temperature on PM 10 concentrations from the tapered element oscillating microbalance (TEOM) method by operating collocated TEOM monitors at different equilibration temperatures in an airshed (the Lower Fraser Valley, British Columbia). This airshed contained an abundance of particulate semivolatile material (PSVM). For the period when three collocated TEOM monitors were operated, the PM 10 from the monitor at an equilibration temperature of 30°C was 2.5 µg/m 3 (22%) and 1.7 (17%) µg/m 3 higher, on average, than the PM 10 from monitors at 50 and 40 °C, respectively, and the differences were proportional to the ambient PM 10 loading. Greater volatilization of PSVM in the TEOM monitors at higher equilibration temperatures may have been a cause of the differences.
