Figure 3. — (a) Chitin signals resolved by 2D ¹³C-¹³C PAR correlation spectrum (top and middle) and 2D ¹⁵N-¹³C correlation spectrum (bottom panel). These spectra were measured using DNP for sensitivity enhancement. (b) Peak multiplicity observed in 2D ¹³C-¹³C CORD correlation spectrum. Dashed lines in orange show the carbon connectivity of type-a and type-d chitin. Dashed lines in green show the signals of type-a (A^a) and type-b (A^b) α−1,3-glucan.
