25-25. Chromatography-mass spectrometry. Cocaine metabolism in rats can be studied by injecting the drug and periodically withdrawing blood to measure levels of metabolites by HPLC-mass spectrometry. For quantitative analysis, isotopically labeled internal standards are mixed with the blood sample. Blood was analyzed by reversed-phase chro- matography with an acidic eluent and atmospheric pressure chemical ionization mass spectrometry for detection. The mass spectrum of the collisionally activated dissociation products from the m/z 304 positive ion is shown in the figure on...

For the following mass spec data: a) Circle the structure(s) consistent with the mass spectrum (more than one answer may be possible): b) Draw the structure(s) of the most abundant fragments (base peaks) in the mass spectrum. If two compounds are consistent with the spectrum, please draw the base peak for each structure)
