How to elucidate molecular structure of unkwon? I have done FTIR, HNMR, CNMR & DEPTH 135. ?

29 January 2024 1 10K Report

Dear respected seniors,

I'm a young ambitious researcher looking for guidance on how to elucidate molecular structure. I have done FTIR, HNMR, CNMR & DEPTH 135 analysis. The expected structure is a cycloolefin polymer. Thank you.

Jean-François Gal

How to elucidate molecular structure is a classical course of organic chemistry. It takes hours of training, and help of an experienced chemist may is useful. For example, the IR spectrum gives me a few basic informations about possible functional groups at first glance, but full, deeper interpretation will take one to several hours looking at correlation tables, books, etc. Same for NMR spectra.
