For example, a proton in a methyl group and a proton in an OH group in methyl alcohol, CH3OH, will have a frequency difference of roughly 7 ppm. Thus, at a resonant frequency of 300 MHz for the proton in the methyl group, the proton in the OH group will absorb at 300 × 106 (...

In NICI, the most abundant ions from methyl abscisate are due to the molecular anion, [M – H2O]− and [M – CH3OH]−. It is shown, however, that the methyl ester methyl is not lost in this last fragmentation. Two other significant ions contain the side chain and the ring of ...

Use of water as the solvent to dissolve the transition metal catalyst provides an advantage over current techniques. Most current systems use a polar solvent such as methanol (CH3OH) to dissolve the nanoparticle catalysts. These systems therefore require polymethylmethacrylate (PMMA) to be used as ...
