q-HMBC for Sensitivity-Enhanced 29Si Quantitation
Maximizing signal-to-noise ratio per measurement time by using the advantages of magnetization transfer in 29Si–1H-HMBC spectra. In a previous application note we discussed how the copolymer composition and average molar mass of poly(dimethylsiloxane-co-methylhydrosiloxane), trimethylsilyl terminated (Figure 1) can be determined by 29Si-DEPT NMR spectra and using a well characterized sample of the same substance as …
