2D HSQC-derived "dark forest" image with enhanced local resolution via first derivative processing-logarithmic cosine transformation (FDP-LCT): Demonstration on per-O-ethylated kappa- and iota-carrageenans
{{output}}
Solution-state two-dimensional (2D) 1H-13C HSQC NMR is a powerful tool for polysaccharide structure elucidation but often suffers from limited sensitivity and broad peaks due to the low natural abundance of 13C and poor digital resolution of the indirect dimen... ...
