Attention in this chapter will be mainly focused on che reaction of tecrahydrofuran (THF) with thin lithium films vapor-deposited in UHV on clean polycrystalline Ag substrates. The techniques employed in this study included TPD, XPS and AES. A parallel study of THF adsorption on Li layers deposited on Au substrates is currently being pursued by Ms. Guorong Zhuang using FTIRRAS (Fourier Transform Reflection Absorption Infrared Spectroscopy) in this laboratory. 

The technique using p-s modulation has received different names depending on the kind of IR instrument used. Thus for grating instruments it was called PMIRRAS (polarization modulation infrared reflection-absorption spectroscopy) [6]. For FT spectrometers the name FTIRRAS [8] was suggested. However this name was later used also in connection with Fourier transform spectra applying the potential difference approach.
