About This Simulation
Help Yummy Food Inc survive the shut down of their food factory! Learn about the principles of the analytical technique carbon-13 NMR and interpret the spectrum of the mysterious unlabelled compound they have used in their food and drink.
Learning Objectives
- Recognize when 13C-NMR techniques can be usefully applied
- Describe the factors that give rise to chemical shifts
- Prepare a sample for 13C-NMR analysis
- Classify the resonances in example 13C spectra and relate them to molecular structure
About This Simulation
Lab Techniques
- Carbon NMR
- 13-Carbon Nuclear Magnetic Resonance (13C-NMR)
Related Standards
- Early Stage Bachelors Level
- Intermediate Stage Bachelors Level
- EHEA First Cycle
Learn More About This Simulation
NMR saves the day! In this simulation, you will learn about the principles of the analytical spectroscopic technique known as nuclear magnetic resonance. Understand the factors that cause the resonance peaks and train your chemistry mind to interpret the complete spectra.
Why Carbon-13?
In our very fun minigame, learn about the characteristics of the carbon-13 nuclei and why the isotope of carbon is detected instead of the carbon-12 we know to be in the periodic table. Explore more features of the atomic nuclei that are important for nuclear magnetic resonance technology such as gyromagnetic ratio and natural abundance.
Chemical Shifts
Why do we get peaks at different chemical shifts? Explore the characteristics of atoms in a functional group that alters the position of the peaks in the Carbon-13 NMR spectra. Learn in more depth the effects of electronegativity, electron induction, and diamagnetic anisotropy and in what molecular examples do these effects take place.
Apply your newly gained knowledge about the functional groups and resonance peaks to interpret the spectra, and grasp how these effects can alter the chemical shift of the peaks. Continue your learning and get some practice using the chemical shift range to identify the presence of functional groups in the molecular structure of your solid sample.
Sample preparation
Let’s go to the lab bench! Familiarise yourself with the process of sample preparation of an organic solid compound. Explore the equipment and the reagents such as the solvents and the reference compound.
Interpret the final spectrum to uncover the molecular structure of the unknown compound.
Become the scientific detective we know you are and solve the ultimate chemystery!

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

Labster can be integrated within a school's LMS (Learning Management System), and students can access it like any other assignment in their LMS. If your Institution does not choose an LMS integration, students will log in to Labster's Course Manager once they have an account created. Your institution will decide the access method during the sales process.
Labster is only available for purchase by faculty and administration at academic institutions. To procure Labster, simply reach out to us on our website. Schedule a demo, book a meeting to discuss pricing, start a free trial, or simply fill out our contact form.
Labster simulations are created by real scientists and designed with unparalleled interactivity. Unlike point and click competitors, Labster simulations immerse students and encourage mastery through active learning.
Labster supports a wide range of courses at the high school and university level across fields in biology, chemistry and physics. Some simulations mimic lab procedures with high fidelity to train foundational skills, while others are meant to bring theory to life through interactive scenarios.
