A chemist records an ESI accurate mass spectrum of an intermediate during a synthesis. The desired compound is C29H31N3O8S. She sees a peak(M+H)^(+) on her ESI-TOF LCMS at 583.1733. The two possibilites for the incorrect feature are A: incoporation of a deuterium at an acidic site from the CDCL3 used for NMR she ran immedately prior LC-MS or B: An amide was hydrolyzed to an acid. Assuming the mass spectrometer is well calibrated, which of these two options is supported by the data. Be sure to explain your answer.
