Effect of Iodine Doping on Bi2Sr2Ca1Cu2Ox - Charge-Transfer or Interlayer Coupling

A comparative study has been made of iodine-intercalated Bi2Sr2Ca1Cu2Ox single crystal and 1 atm O2 annealed Bi2Sr2Ca1Cu1Ox single crystal using an AC susceptibility measurement, X-ray photoemission (XPS) and angle-resolved ultraviolet photoemission spectr ...

Control by density effects of the Rydberg-valence configuration mixing in matrix isolated NO

Majed Chergui

D. effects and N2 co-doping of Kr solids doped with NO allow continuous tuning of the NO Rydberg state energies in a range 0.35 to 0.68 eV blue of the gas phase. This property is exploited to control the vibronic configuration mixing between the Rydberg C2 ...

Multiple oscillations observed in the rotational state population of molecular iodine(B) formed in the photodissociation of the molecular iodine dimer((I2)2)

Hubert van den Bergh, René Monot

Several oscillations are obsd. in the rotational state population of I2 B3P(Ou+) produced in the photodissocn. (I2)2 + hn -> I2(Bu',J') + I2(X). The initial excitation is above the dissocn. limit of the I2 B state. These oscillations are pronounced on some ...

Photodissociation of iodine complexes in relation to the cage effect

Hubert van den Bergh, René Monot

The photodissocn. I2M + hn -> I2 + M was studied for M = C2H6 and M = (C2H5)2O with excitation above the dissocn. limit of I2B state. Vibrational population distributions of the I2(B) product mols. are reported. The results are compared to previous studies ...

Solvent caging by diatomic molecules in the photodissociation of molecular iodine-diatomic molecule (I2M) clusters

Hubert van den Bergh, René Monot

The reaction I2M + hn -> I2(B) + M (M = H, N, O, I) was studied following excitation of the I2M cluster above its B state dissocn. limit. Dispersion of the I fluorescence allows for the detn. of the relative populations of a no. of the vibrational levels v ...

On the possibility of nonadiabatic transitions in the photodissociation of molecular iodine-rare gas atom complex (I2M) clusters excited above the dissociation limit of the B state

Hubert van den Bergh, René Monot

The reaction I2M + hn -> I2(B,v',j') + M (M = rare gas atom) was studied exptl. for excitation above the dissocn. limit of the I2M B state. A surprisingly large amt. of the available energy is found as relative translational energy of the I2 and M products ...

The photolytic cage effect of iodine in gases and liquids

Hubert van den Bergh, Matthieu Philippe Emmanuel Zellweger

The photolytic cage effect was studied over a wide d. range of several bath gases in the laser flash photolysis of I2 at 694.3 nm. Particular attention was paid to measurements in the simple solvents Xe and Kr, which were compared with mol. dynamics calcns ...

The photolytic cage effect of iodine in the gas phase

Hubert van den Bergh, Matthieu Philippe Emmanuel Zellweger

The laser flash photolysis of I was studied over a wide pressure range in several bath gases. At low pressures the obsd. quantum yield for photolysis at 6943 .ANG. is independent of the gas d., whereas at higher pressures the quantum yield decreases with i ...

Kinetic and thermodynamic properties of nitrosyl iodide and nitryl iodide intermediate complexes in iodine recombination

Hubert van den Bergh

The recombination of I atoms after laser flash photolysis was studied in the presence of NO or NO2 at 320-450 DegK and 0-200 atm of He. The reaction proceeds in 2 stages. The 1st stage is governed by the recombination I + NO (+He) -> INO (+He) or I + NO2 ( ...

Nitrogen oxide-catalyzed recombination of iodine atoms. Elementary steps of the complex mechanism

Hubert van den Bergh

The recombination of I atoms in the presence of NO was studied by laser flash photolysis in the inert gas He, at pressures between 1 and 200 atm and at temps. from 320-440 DegK. The elementary steps of the complex mechanism of the recombination were resolv ...
