No two carbons are in exactly the same environment. The peak at just over 50 must be a carbon attached to an oxygen by a single bond. The two peaks around 130 must be the two carbons at either end of a carbon-carbon double bond. The peak at just less than 170 is the carbon in a carbon-oxygen double bond.Make an account at Colorado PEAK and download the free Health Colorado app. Use the MyCOBenefits app to take control of your Food (SNAP) and Cash assistance benefits!
