Cyclooctadiene iridium methoxide dimer is an organoiridium compound with the formula Ir 2 (OCH 3) 2 (C 8 H 12) 2, where C 8 H 12 is the diene 1,5-cyclooctadiene. It is a yellow solid that is soluble in organic solvents. The complex is used as a precursor to other iridium complexes, some of which are used in homogeneous catalysis. [1]
The range for one-bond 1 J(13 C, 13 C) is 50–130 Hz. Two-bond 2 J(13 C, 13 C) are near 10 Hz. The trends in J(1 H, 13 C) and J(13 C, 13 C) are similar, except that J(1 H, 13 C are smaller owing to the modest value of the 13 C nuclear magnetic moment. Values for 1 J(1 H, 13 C) range from 125 to 250 Hz. Values for 2 J(1 H, 13 C) are near 5 Hz ...
Triple resonance experiments are a set of multi-dimensional nuclear magnetic resonance spectroscopy (NMR) experiments that link three types of atomic nuclei, most typically consisting of 1 H, 15 N and 13 C. These experiments are often used to assign specific resonance signals to specific atoms in an isotopically-enriched protein.
Proton nuclear magnetic resonance (proton NMR, hydrogen-1 NMR, or 1 H NMR) is the application of nuclear magnetic resonance in NMR spectroscopy with respect to hydrogen-1 nuclei within the molecules of a substance, in order to determine the structure of its molecules. [1]

As well as winning they beat the old standing record of 306 km/liter (326.8 cm 3 /100 km), set by the same team in 2007. [ 27 ] To study the dimethyl ether for the combustion process a chemical kinetic mechanism [ 28 ] is required which can be used for Computational fluid dynamics calculation.
