Results Proton Spectra (Table 1). A sample of 0.6 mL of the solvent, containing 1 ?L of TMS,1 was first run on its own. From this spectrum we determined the chemical shifts of the solvent residual peak2 and the water peak. It should be noted that the latter is quite temperature(1)...

A new modified singular value decomposition method, piecewise polynomial truncated SVD (PPTSVD), which was originally developed to identify discontinuity of the earth's radial density function, has been used for large solvent peak suppression and noise elimination in nuclear magnetic resonance (NMR) si...
