143C Spectroscopic Elucidation Project

OBJECTIVE:

Students will be tasked to create a presentation based on a publication describing the structural

elucidation of an organic molecule. This project will demonstrate the student’s ability to

interpret the data and critically analyze the elucidation methods. This project will also

demonstrate the student’s proficiency in science communication.

SCOPE:

Each student will be given the freedom to explore the literature and present an elucidation of

their choice (with TA or instructor approval). The publication must describe a structural

elucidation based on, at minimum, mass spectrometry (MS), nuclear magnetic resonance

(NMR, 13C and 1H) spectroscopy, and one other spectroscopic analytical method (i.e. IR, 2D-

NMR, UV-Visible Spectroscopy, etc.)

Students will prepare a critical analysis (not just a description) of the elucidation methods

detailed in the publication for a verbal Powerpoint presentation. Presentations will be recorded

on Zoom using Cindy Tran’s (143B Lab Staff) account, which will be automatically be

uploaded onto Canvas. You will need to sign up for a designated recording time slot by

November 18-19.

The presentation must meet the following criteria:

• Presentation time limit: 5-10 minutes

• Presentation slide limit: 8-10 slides

• Presentation of data AND rationalization/justification of why the data are important: you will focus on one piece of spectral data that you believe (not necessarily what the

authors say) was key to assigning the structure and provide your justification why these

data were critical in assigning the structure

• Also, you will need to include your assessment of the of the elucidation. Propose other methods that could have been done and what information they would hypothetically

provide.

SUBMISSION DATES

• October 26-27: Journal Article Submissions due

• October 28-29: Article Approved, Draft Outline due

• November 18-19: Presentation Draft Slides due, Recording Date Selection due

• November 22-23: Project Slides due

• December 7-8: Presentations recorded

The following is an outline of the presentation format:

ONE SLIDE ONLY

Title slide: Analysis of “The structural elucidation of …..” by Joey Bag of donuts, et al; J. of

Irreproducible results, 2000, 23, 100-101.

By: Student Name

*NOTE: your citations MUST be in ACS citation format.

ONE SLIDE ONLY

Introduction: Where the product was isolated? How was it isolated? How was it purified? What

was the purity level and method used for the evaluation of percent purity?

2 SLIDES

Present critical data related to structural determination with explanations in a logical order.

2-3 SLIDES

Student analysis of data including the key data that were crucial for the elucidation (without

which the elucidation would not be as good/possible)…be specific; not just “NMR” but “the

2D NMR showing the stereochemistry of….”

1-2 SLIDES

Student evaluation/critique of the quality of the structure: 99+% certain, etc. with justification.

What other data could be obtained to firm up the structure?
