Solvent dependence of the νs(OD) bandshape in 2,6-dichlorophenol

1994

Abstract The infrared bandshape of νs(OD) of 2,6-dichlorophenol is measured in a series of solvents of increasing polarity, and is quantitatively analysed. The bandshape is described in terms of band indices, moments, correlation functions and correlation times. A distinct solvent dependence of bandshape and relaxation parameters has been found. The changes of the νs(OD) bandshape with increasing solvent polarity are compared in detail with those obtained earlier for analogous solvents for νs(OH) of 2,6-dichlorophenol. The overall behaviour of the spectral and relaxation parameters is similar, but the changes are less distinct for the weaker OD ⋯ Cl bond.

Magnetic dichroism in angle-resolved hard x-ray photoemission from buried layers

2011

This work reports the measurement of magnetic dichroism in angular-resolved photoemission from in-plane magnetized buried thin films. The high bulk sensitivity of hard x-ray photoelectron spectroscopy (HAXPES) in combination with circularly polarized radiation enables the investigation of the magnetic properties of buried layers. HAXPES experiments with an excitation energy of 8 keV were performed on exchange-biased magnetic layers covered by thin oxide films. Two types of structures were investigated with the IrMn exchange-biasing layer either above or below the ferromagnetic layer: one with a CoFe layer on top and another with a Co${}_{2}$FeAl layer buried beneath the IrMn layer. A pronou…
