When an animal uses carbon from a c4 plant, the ratio of c12 to c13 will be the same as in the plant. The expanded region below shows 4 signals. The 4 weak signals follow a quartet pattern produced by a cf3.

Of tms in cdcl3, it is necessary to measure the chemical shifts of the reference compounds, the now possible to tabulate accurate measurements of proton and deuterium chemical shifts of tms and residual solvent and water signals in several common nmr solvents over a wide temperature range.

Why do we habe 3 peaks for cdcl3 in nmr 13c? Calibrate the chemical shift with the cdcl3 carbon, set as 77.0ppm. Of tms in cdcl3, it is necessary to measure the chemical shifts of the reference compounds, the now possible to tabulate accurate measurements of proton and deuterium chemical shifts of tms and residual solvent and water signals in several common nmr solvents over a wide temperature range. Does it come from deuterium or chlorine?
