ABSTRACTA study was made of third-order nonlinear optical susceptibilities of new tetrathiafulvalene (TTF) derivatives, using the degenerate four wave mixing (DFWM) method, as well as complex quantum chemical calculations. To understand the physical nature of the optical nonlinearities, we separated their electronic and nuclear contributions. We found that the electronic contribution to these nonlinearities predominated. Our investigations suggest that TTF may be a highly promising material for nonlinear optics (NLO).

The effect of a newly synthesized TRIS-based Schiff base (XC) on the oxidative dissolution of FeS in air-equilibrated solutions with pH 2.26 and temperature of 27�C was investigated by Potentiodynamic polarization, Cyclic Voltammetry, Optical Microscopy and quantum chemical calculations. The XC concentration varied between 0 and 0.52 mM. It was observed that XC decreases the corrosion current densities of the oxidative dissolution of FeS. Our results indicate that the inhibitory effect of XC is due to its adsorption on the FeS surface.
