6. Analysis of racemic fluoxetine hydrochloride by mass spectrometry gave, unsurprisingly, a main peak of exactly the same m/z value as that observed for either enantiomer in pure form. The mass spectrum of (S)-fluoxetine oxalate also showed the same main m/z peak. Explain these observations. [The molecular formulae of (R)- and (S)-fluoxetine hydrochloride is C17H19CIF3NO; the molecular formula of (S)-fluoxetine oxalate is C19H20F3O5.]
