Fig. 21. 121.5 MHz HEED-DEPT spectra of 2-fert-butyl-l,3-dimethyl-...

FIGURE 45. 29Si spectra of HN(SiMe3)2 (at 71.55 MHz, 80% in CgDf, 10 mm sample tube, 2 K data points zero-filled to 8 K) acquired (a) with INEPT (16 transients) (b) the same as (a) after Gaussian multiplication (LB = —1 Hz, GB = 0.7) (c) with DEPT (16 transients) — note the effect of the longer sequence (d) with HEED-INEPT (64 transients, x = 35.7 ms, A = 19.06 ms, T = 0.3 s).
