Spectrus: Correlating IR and NMR data to confirm functional groups

Description
IR and NMR provide complementary information about functional groups. Using both in a single Spectrus project helps confirm structural assignments.

Solution

1. Import both IR and NMR spectra for the sample into the same Spectrus record or project.
2. In the IR spectrum:
   • Identify bands associated with key functional groups (C=O, O–H, N–H, etc.).
3. In the NMR spectra:
   • Locate protons or carbons consistent with these groups (e.g., aldehydic protons, alpha‑to‑carbonyl shifts).
4. Cross‑check:
   • A strong C=O stretch in IR should correlate with appropriate NMR shifts (e.g., deshielded 13C, alpha protons).
5. Use this combined evidence to:
   • Confirm the presence or absence of proposed functional groups.
   • Strengthen overall structural assignment in reports.
