Spectroscopy Problems II. Eight structure elucidation problems based on 1 H nmr, 13 C nmr and infrared spectroscopic data are presented below. In each case, from the nineteen formulas shown at the bottom of the page (A through S), select that one which best fits the evidence. Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of oct‐1‐en‐3‐ol [02.023], pent‐1‐en‐3‐ol [02.099], oct‐1‐en‐3‐one [07.081], oct‐1‐en‐3‐yl acetate [09.281], isopulegol [02.067] and 5‐methylhept‐2‐en‐4 ...
