Ethyl acetate ¹³C NMR: C=O δ 171, OCH₂ δ 60, CH₃C=O δ 21, CH₃ δ 14 (CDCl₃ triplet at 77.2), with a ¹³C chemical-shift ranges chart on the same axis. ## What the template shows - Four carbon environments, four singlets (proton-decoupled), on the 220 → 0 ppm scale with the shift-range chart below - Spectrum (CDCl₃, 100 MHz, typical values) and shift ranges - δ / ppm (¹³C, proton-decoupled) - ethyl acetate, C₄H₈O₂ - why there - ester carbonyl (155–185); quaternary C: small peak - Typical ¹³C chemical shifts - Ketone, aldehyde C=O - Acid, ester, amide C=O - RCO₂H, RCO₂R′, RCONR₂ - alcohol, ether, ester - Number of signals = number of carbon environments (4 here). Spectra are normally proton-decoupled, so every carbon is a singlet. - Peak heights are not proportional to the number of carbons; quaternary C (C=O here) are usually small. - The ¹³C range is about 0–220 ppm, so signals rarely overlap. - C=O of acids, esters and amides: 155–185; ketones and aldehydes: 185–220. - The CDCl₃ solvent gives a 1:1:1 triplet at δ 77.2 (coupling to ²H, spin 1). - Simulate and compare spectra in the free MolDraw NMR viewer (moldraw.com/tools/nmr-viewer). - Typical literature values; compare real spectra in SDBS · every part of this figure is editable Drawn with 6 atoms, 141 shapes – every one editable in MolDraw. ## Sources - [Pavia, Lampman, Kriz & Vyvyan, Introduction to Spectroscopy, 5th ed., Cengage 2015, ch. 4](https://openlibrary.org/isbn/9781285460123) Textbook - [Silverstein, Webster, Kiemle & Bryce, Spectrometric Identification of Organic Compounds, 8th ed., Wiley 2014](https://openlibrary.org/isbn/9780470616376) Textbook - [SDBS Spectral Database for Organic Compounds (AIST)](https://sdbs.db.aist.go.jp/) Database ## How to use this template 1. Press **Edit in MolDraw**. The template opens on the canvas of the free MolDraw editor. 2. Change anything: move structures, edit atoms and labels, recolour highlights or delete what you do not need. 3.

Export the drawing as PNG, SVG or PDF for slides, worksheets, theses and papers. ## Frequently asked questions ### Is the ¹³C NMR of ethyl acetate template free? You can preview the ¹³C NMR of ethyl acetate template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates. ### Can I edit the ¹³C NMR of ethyl acetate template? Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it. ### Is the chemistry checked? Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page. ### Are the spectra real data? The spectra are schematic, drawn to the standard chemical shifts, splitting patterns and absorptions given in textbooks, so they are clear for teaching and exam practice. ## More spectroscopy templates [**¹H NMR of ethanol**Free · Spectroscopy](https://www.moldraw.com/templates/spectro-h-nmr-ethanol/)[**Spin–spin splitting: the n + 1 rule**Free · Spectroscopy](https://www.moldraw.com/templates/spectro-n-plus-1-rule/)[**IR spectra: ketone, alcohol and carboxylic acid**Free · Spectroscopy](https://www.moldraw.com/templates/spectro-ir-functional-groups/)[**¹H NMR of ethyl acetate**Premium · Spectroscopy](https://www.moldraw.com/templates/spectro-h-nmr-ethyl-acetate/)[**¹H NMR of toluene**Premium · Spectroscopy](https://www.moldraw.com/templates/spectro-h-nmr-toluene/)[**¹H NMR chemical-shift ranges**Premium · Spectroscopy](https://www.moldraw.com/templates/spectro-h-shift-chart/)[**IR key absorptions**Premium · Spectroscopy](https://www.moldraw.com/templates/spectro-ir-key-absorptions/)[**Mass spectrum of pentan-2-one**Premium · Spectroscopy](https://www.moldraw.com/templates/spectro-ms-pentan-2-one/) ## Related pages [**All Spectroscopy templates**11 templates](https://www.moldraw.com/templates/spectroscopy/)[**All chemistry templates**370 templates in 29 categories](https://www.moldraw.com/templates/) MolDraw Pro Download all 370 templates - Export the 291 premium templates as PNG, SVG or PDF - AI chemistry assistant - Structure scanning from images - Cloud save and teaching slides [See Pro plans](https://www.moldraw.com/pricing) Free templates stay free.
