Cdcl3 Solvent Peak. The standard for chemical shift is dilute tetramethylsilane (tms) in cdcl3, but many measurements are made relative to tms in other solvents, the proton resonance of the. Common solvent peak coupling and chemical shift values.

A common solvent for dissolving compounds for 1h and 13c nmr spectroscopy is deuteriochloroform, dccl3. It should be used whenever possible (<10 pence/sample).
