  Structure Elucidation of Phenylephrine and Ephedrine PHENYLEPHRINE The most stable conformation was obtained by Vconf software. The number of conformations of phenylephrine are 45. The lowest energy conformation with energy 12.8 and the number of conformations and lowest energy conformations of ephedrine are 19 and 13.78 respectively. It is optimized using Gaussian software. This section will explain the chemical composition of Phenylephrine and Ephedrine. EPHEDRINE Phenylephrine has a molecular formula of C 9 H 13 NO 2  and its structure consists of a phenethylamine core with a substituted hydroxyl group. The molecule contains several types of bonds including carbon-carbon (C-C), carbon-hydrogen (C-H), carbon-oxygen (C=O), and carbon-nitrogen (C-N) bonds. The geometry around the carbon atoms is primarily tetrahedral, with the substituents determining the specific spatial arrangement around each carbon atom. Phenylephrine consists of 25 atoms,90 electrons with two ...
