A chemist is summoned to an abandoned waste-disposal site to determine the contents of a leaking, corroded barrel. Thebarrel reeks of an overpowering fishy odor. The chemist dons a respirator to approach the barrel and collect a sample,which she takes to her laboratory for analysis.The mass spectrum shows a molecular ion at m>z 101, and the most abundant fragment is at m>z 86. The IR spectrum shows no absorptions above 3000 cm-1, many absorptions between 2800 and 3000 cm-1, no absorptions between1500 and 2800 cm-1, and a strong absorption at 1200 cm-1.
