Abstract. The principles behind the operation of a nuclear magnetic resonance spectrometer and an infrared spectrophotometer were fairly easy to explain to students fifteen years ago. As NMR and IR instruments became FTIR and FTNMR instruments, students understanding of these important chemical tools became vague to nonexistent. Furthermore, the task of a teacher to explain them to the students became more difficult. The audio-frequency analogy presented here is offered as a plausible technique for presenting these difficult ideas to chemistry students.
