The Application of Simple and Easy to Implement Decoupling Pulse Scheme Combinations to Effect Decoupling of Large Values with Reduced Artifacts
Figure 7
The 31P NMR spectrum of HP(=O)(OCH2CH3)2 indicates the relative sensitivities of the resultant signal with decoupling of 1H by (a) CW decoupling (PL, 5 dB; , 3.85 Hz; DB, ~45 Hz; SDB, irrelevant) and (b) CPD decoupling using WALTZ (PW, 45 μs; PL, 6 dB; , 1.45 Hz; DB, 15 kHz; SDB, 3 kHz) and (c) the same as (a) except with the application of 0 Hz line broadening to reveal the residual coupling to the methylene protons.
