Sentence examples for methyl and two from inspiring English sources

C hyperfine couplings for the methyl and two methoxy groups of SQi generated in situ in the native complex in its membrane environment were determined by 2D ESEEM (HYSCORE).

Moreover, two methyls and two bulky isopropyls on the phenylene rings led to the distorted polymer chain, which significantly reduced the chain packing density and disturbed the alignment of polymer chains along the substrate surface, and consequently resulted into the polymer films low refractive indices and birefringences.

The H NMR spectrum demonstrated signals for six tertiary methyl groups and two secondary methyl groups ranging from δ 0.64 to 1.64, three olefinic protons at δ 4.66 (2H) and 5.22 (1H), and a deshielded methine proton at δ 3.22.

Nevertheless there were obvious differences: the absence of a trisubstituted double bond signals, a doublet methyl signals and two high field methylene signals, instead a saturated carbonyl carbon signal and four oxygen-bearing carbon signals were observed.

Among saturated fatty acids, dodecanoic acid, lauric acid (C12 0), methyl myristate and three hexadecanoic acid methyl esters including palmitic acid (C16:0) and methyl non-adecanoic acid were identified, while saturated fatty acids including two linoleic acid methyl esters that were 9, 12 octadecadienoic acid and one linoleic acid isopropyl ester were identified.

The method was applied on six routes to methyl methacrylate and ten routes to acetic acid.
