Abstract. In this work, a two-part molecular modelling activity for an introductory infrared spectroscopy undergraduate laboratory experiment is described. iSpartan, a molecular modelling app available for hand held devices, is used to illustrate the relationships of bond strength and atomic mass with spectral band location. The foundational functional groups are also examined using the app, which results in a student generated IR correlation table.

Key Words: Computers in Chemistry; organic chemistry; infrared spectroscopy; molecular modelling app
