Abstract
This is a collection of six documents that can be used to teach and learn the basic concepts of FT-IR. The first document, ft_notes.mcd, 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 ft_01_6.mcd students are introduced to the parameters that affect resolution and spectral width. Document ft_02_06.mcd shows how two frequency components add to give a beat pattern. The emphasis in ft_03_6.mcd is on how cosine and sine waves describe the frequency and phase of a signal. In ft_04_6.mcd students can examine the effect of an exponential decay in the time domain and frequency domain. The entire series of documents is summarized in ft_05_6.mcd. 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
