1H VFMAS spectra of (a) Cu(L-Ala)2 and (b) L-Ala obtained at the 1H NMR frequency of 400.2 MHz with one-pulse excitation at the spinning speed of 28.57 kHz. The sample amounts are (a) 20 nmoles (5 μg) and (b) 40 nmoles (4 μg). An experimental time was 2 min each. A total of (a) 38,700 and (b) 76 scans were recorded with recycle delays of (a) 3 ms and (b) 1.6 s, respectively. Background signals and spinning sidebands are marked by # and *, respectively. The spectrum (a) is scaled so that the two spectra display a common noise level. The data were modified from ref. 17.
