Pressure dependence of weak acid ionization in deuterium oxide solutions
Article Abstract:
The pressure dependence of solution pH for acetate, cacodyte, phosphate and TRIS buffers in deuterium oxide solutions has been investigated. Pressure dependence was measured with the optical pH indicatoe 2,5-dinitrophenol and p-nitrophenol up to a pressure of 300 MPa. The results showed that the pressure dependence for these compounds was not changed by the isotope substitution. The study concluded that the volume changes associated with the ionizations were not affected by isotope effects in the water.

Intracluster chemistry in [Cr(CO)6]n
Article Abstract:
The ultrafast intracluster bimolecular chemistry occurring in homogenous transition metal carbonyl clusters [Cr(CO)6]n was investigated through one-color femtosecond-pump/probe experiments. Most transients measured at lower photon energy were found to exhibit faster dynamics than those at higher photon energy. This finding can be explained by the presence of additional reaction products at higher photon energy that show up as different oxides and carbines.

Photoinduced Rydberg ionization (PIRI) spectroscopy of the B state of the fluorobenzene cation
Article Abstract:
The photoinduced Rydberg ionization (PIRI) spectra of the B state of the fluorobenzene cation were investigated using vibrational analyses and ab initio calculations. The spectra observed through various ground-state nonsymmetric vibrations indicated that the B <- X transition is allowed since line positions do not support a forbidden assignment. Ab initio calculations, though inconclusive, also supported the B <- X transition.
