Spectroscopy and the Fourier Transform

As a result of the sudden growth of Fourier transform spectroscopy (FTS) over the last two decades, many spectrometers are used in labs by people who do not understand their operation. This problem is compounded by the sophisticated use of the computer by FTS. Understanding FTS is a difficult task because the concepts are alien to many and, to complicate matters, the mathematics involved are just as confusing. This book is written to address this problem directly. The functioning of the inferometer is presented as if it were constructed from dispersive components. The Fourier transform itself is presented in a graphical, rather than mathematical fashion.
