This is a collection of six documents that can be used to teach and learn the basic concepts of FT-IR. The first document,, provides an introduction to FT. It displays the mathematics in such a way that it can be used as a lecture handout or interactive student activity. With students are introduced to the parameters that affect resolution and spectral width. Document shows how two frequency components add to give a beat pattern. The emphasis in is on how cosine and sine waves describe the frequency and phase of a signal. In students can examine the effect of an exponential decay in the time domain and frequency domain. The entire series of documents is summarized in This last document contains large fonts and no explanatory text. It is designed for use in class lectures. A description of the documents can be found in "Using Mathcad to Teach Instrumental Techniques" J.Chem. Educ. 75, 1998, pp 375-378. The documents described here all require Mathcad 6.0 or higher. A single document containing the concepts in the five given here was published by the Journal of Chemical Education, J. Chem. Educ. 76, 1999, p286
