Abstract. This paper describes how isotope and atomic-weight concepts are enhanced for students using mass-spectral data from interactive Internet sites. The class considers mass spectra for compounds containing only monoisotopic elements and later for polyisotopic elements. Students calculate molecular weights based on data they acquire from mass spectra on the Internet.
