Various molecular species are known to form during the photoreaction of C2H4I2 in the gas phase and in solution. We have studied all species involved in this reaction by ab initio and density functional theory (DFT) calculations: Geometries, energies, and

This study presents a method to measure the contact angles of oils on a substrate in water. Diiodomethane and perfluorodecalin were used as model oils. Self-assembled monolayers (SAMs) were prepared by adjusting the mole ratio of CH 3- and OH-terminated

We report direct structural evidence of the bridged radical (CH2ICH2.) in a polar solution, obtained using time-resolved liquid-phase x-ray diffraction. This transient intermediate has long been hypothesized to explain stereo-chemical control in many association and/or dissociation reactions involving haloalkanes. Ultrashort

UV excitation of jet-cooled CH2OO X(1)A' to the excited B(1)A' electronic states results in dissociation to two spin-allowed product channels: H2CO X(1)A1 + O (1)D and H2CO a(3)A″ + O (3)P. In this study, the higher energy H2CO a(3)A″ +

Flash photolysis (FP) coupled to resonance fluorescence (RF) was used to measure the absolute rate coefficients (k(1)) for the reaction of OH(X(2)Π) radicals with diiodomethane (CH(2)I(2)) over the temperature range 295-374 K. The experiments involved time-resolved RF detection of the
