H-NMR Spectrum : The spectrum obtained by H-NMR tells us about the types of hydrogen atoms and also about the number of hydrogen atom present on the neighboring carbon atoms. The main peak obtained for particular type of hydrogen atoms splits into N+1 peaks where N is the no of hydrogen...
The 29Si and 27Al MAS NMR spectra was recorded on a Bruker AVANCE-III spectrometer operating at 79.50 MHz (29Si) and 104.26 MHz (27Al) equipped with a CP-MAS 4 mm solid state probe. The 27Al spectra were recorded using a 5.00 µs pulse and a recycle delay of 0.05 s at 14 kHz...
