Vibrational Spectra and Surface-Enhanced Vibrational Spectra of Azamacrocycles

This chapter has been organized by considering several aspects. An introduction concerning the relevance of the electronic properties and applications of the azamacrocycles related to surface phenomena as well as the general aspects and characteristics of the vibrational techniques, instruments and surfaces normally used in the study of the adsorbate–surface interaction. The vibrational enhanced Raman and infrared surface spectroscopies, along with the reflection– absorption infrared spectroscopy to the study of the interaction of several azamacrocycles with different metal surfaces are discussed. The analysis of the most recent publications concerning data on bands assignment, normal coordinate analysis, surface-enhanced Raman and infrared spectroscopies, reflection– absorption infrared spectra and theoretical calculations on models of the adsorbate–substrate interaction is performed.
