cis Versus trans-Azobenzene: Precise Determination of NMR Parameters and Analysis of Long-Lived States of 15N Spin PairsWe provide a detailed evaluation of nuclear magnetic resonance (NMR) parameters of thecis- andtrans-isomers of azobenzene (AB). For determining the NMR parameters, such as ...
The chemical sample used in the experiment was a mixture of cis and trans isomers of 1,2-dibromoethene. In the cis isomer, the two bromine atoms, each attached to one of the two carbon atoms, are pointing in the same hemisphere with respect to the C=C double bond, while they are...
The coloration of triphenylethylene mainly comes from the photo-triggered cyclization of cis-isomers. The initial attenuation of TP-Cl and TP-Br under UV irradiation is mostly caused by cis–trans photoisomerization, rather than the oxygen-involved photooxidation reactions. Based on the controllable "...
This is the first examination of these two mechanisms for both cis and trans isomers of a system employing two monodentate ligands. It is the first case of acid-assisted reductive elimination from a square planar Pd-H. The calculated mechanisms indicate that cis/trans isomerization is feasible ...

Conjugated linoleic acids (CLA) are a class of positional, geometric, conjugated dienoic isomers of linoleic acid (LA). Dietary CLA supplementation results in a dramatic decrease in body fat mass in mice, but also causes considerable liver steatosis. However, little is known of the molecular ...
In dichloromethane solution complex 2 displays a chemically reversible Ru(II)/Ru(III) oxidation with formal electrode potentials of −0.27 V (versus the ferrocene/ferricinium couple), whereas 3, trans,trans,trans-[RuCl2(Mepym)2(PPh3)2] (5) and trans,trans,trans-[RuCl2(Thz)2(PPh3)2] ...
