摘要：

C-13 CP MAS NMR spectroscopy was used to characterize alpha-C:H materials generated from methane and hydrogen mixtures using a microwave plasma. Dipolar dephasing experiments indicate a range of T(dd) making quantification of quaternary ''diamond''-like carbons difficult. Unconstrained lineshape analysis is not suitable for the deconvolution of the NMR spectra, but linewidth constrained analyses gave reasonable results. (C) 1993 John Wiley & Sons, Inc.
