The following components were used in generating the plot: Additonal code used was developed at NIST: It is recommended to provide more analysis for each signal than what is described above, when necessary, such as labeling any coupling constants if any are provided. The water layer was drained to the respective beaker while the remaining ether layer was drained into a dry 100ml beaker labeled ether layer. 100mg of the drying agent (magnesium sulfate) was then added to the ether layer and swirled for some time. OH should be approximately 3200-3550 cm-1. iss facility services head office.
Label the hydrogen atoms on the structure: a, b, c, d so that they correspond with the labels for the signals on the spectrum (i.e., match each signal to its appropriate H atoms). 1

If not that might explain your results. It will also have a C-O For example: 3H, singlet, O neighbors, and c (the letter referring to the corresponding unique type of hydrogens that were labeled in the structure). The following IR and NMR spectra are of a compound with the molecular formula of MF C5H12O. The bromobenzene was first transformed into the Grignard compound and was then reacted with the benzophenone to make the final product.
