Some controversy exists on the origin(s) of phase anomalies observed in 13 C FT NMR spectra. Two separate explanations, based on either echo or sampling effects, have been proposed by previous workers. We now show experimentally that these two effects can occur separately or together and, in the latter case, the effects can interfere with one another. Methods to ameliorate or remove phase anomalies are briefly reviewed.
