Reference deconvolution with the FIDDLE algorithm was successfully used for line shape correction of a C-13 spectrum with poor signal-to-noise ratio. Over 70 long-range proton-C-13 correlations were determined with the HMBC experiment, following modifications to improve instrument signal reproducibility, illustrating the value of this experiment when applied to systems with relatively few protons.}, isbn = {0749-1581}, url = {://WOS:A1992KC60000022}, author = {Pant, G. and Nautiyal, A.
