The 100th blog: a Milestone in Structure Elucidation

Structure elucidation is a skill learnt through years of practice. One of the best ways to learn is to learn by example. I feel that there is no better way to do this than mentoring through specific scenarios step-by-step. My intentions behind this blog are to offer a unique source for chemists who use a variety of tools such as NMR, MS, IR, etc. to determine the structural composition for an unknown.


Here are my top 10 picks for P2C2E that I feel have the most potential to impact a chemist who is learning to do elucidations of unknown compounds.


10. Molecular ion or adduct? - Identification of Adduct Ions


9. Missing a peak? - Hampering Data Interpretation


8. Exercise, exercise - The Coupling Exercise


7. NMR, MS, oh my! - Using complementary elucidation tools to solve for an unknown structure


6. Strong coupling? What’s that? - Interpreting strong coupling information from a 1H NMR spectrum


5. Problem Solver - Gearing up the Right Thought Process for Solving Problems


4. I can’t solve this - Stuck on a Structure Elucidation problem? You need Out of the Box thinking, right?


3.  1 + 1 = 1 - Assembling a set of Fragments to Complete a Candidate Structure


2. I need more data? - Why collect NMR or MS^n data? 


1. A 1H NMR is not enough? - Is it possible to elucidate an unknown with just a 1H NMR spectrum?
