Abstract

A new multiple external reflection unit for IR surface studies is described. The unit allows 14 or more reflections at near-grazing incidence, increasing the sensitivity over transmission by 78 and by 111 over a single reflection at 45°. Spectra of sub-monolayers on gold demonstrate the increased sensitivity.
