Synchrotron radiation FT-IR polarized micro-spectroscopy has been used to investigate the natural mica fluorophlogopite in order to characterize the stretching vibrations of the OH groups and their orientation relative to the mica cleavage (0 0 1) plane. A procedure to eliminate undesired interference fringes, typically observed when working with thin single-crystals, was set up using an ad hoc sample preparation, and tested. The naturally high brilliance and high polarization properties of synchrotron radiation allows to study very small flakes and hence offers new analytical possibilities in comparison to conventional powder FT-IR spectroscopy.

Abstract
Synchrotron radiation FT-IR polarized micro-spectroscopy has been used to investigate the natural mica fluorophlogopite in order to characterize the stretching vibrations of the OH groups and their orientation relative to the mica cleavage (0 0 1) plane. A procedure to eliminate undesired interference fringes, typically observed when working with thin single-crystals, was set up using an ad hoc sample preparation, and tested. The naturally high brilliance and high polarization properties of synchrotron radiation allows to study very small flakes and hence offers new analytical possibilities in comparison to conventional powder FT-IR spectroscopy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
