Print the region from 10 ppm to 0.5 ppm for every spectrum you take. 1. Draw the expected structure on the spectrum, and label it with your notebook page number. 2. Number the hydrogens on your drawing and assign them (with labels) to the peaks in the spectrum. ...
While one-dimensional NMR provides a spectrum with peaks along a single axis, two-dimensional NMR (2D NMR) correlations peaks in two dimensions, offering insights into spatial proximity and connectivity between different nuclei. Techniques like COSY (Correlation Spectroscopy), HSQC (Heteronuclear ...

49 peaks in both species, including alcohols, amino acids, fatty acids/esters, nitrogenous compounds, organic acids, phenolic acids, steroids, and sugars, from which data analyses recognized that the bottle gourd was further enriched with fatty acids in contrast to higher sugar levels in cucumber....
For the analysis of short-range ordered structure of starch, height of the peaks found around 1042 and 1019 cm−1 was used to evaluate the properties of the crystalline and amorphous structures of starch, respectively. Lastly, thermal properties were evaluated based on the onset temperature (To...
