WebThe C=S stretching frequency in thiofenchone has been found around 1180 cm −1 which is in fair agreement with the value calculated for thioformaldehyde. In the case of the thiocarbonyl derivatives where the C=S group is linked to elements other than nitrogen, the stretching frequency is generally found in the region 1025–1225 cm −1. WebApr 11, 2024 · The formation of GA-CS conjugate was confirmed by 1 H NMR and FTIR (Fig. 1 b and c). Compared with the 1 H NMR spectra of CS, chemical shifts of 1.405 ppm and 0.486 ppm were observed for GA-CS, which were ascribed to the protons in the -CH, -CH 2 , -CH 3 groups of GA, indicating that the GA was successfully grafted onto the …
