Abstract
Regular-reflection IR spectroscopy is revisited in view of non-destructive in-situ analyses of historical varnishes. The angle dependence of the average level of reflectance as well as of the sign and the amplitude of the dispersion-like features the reflection spectrum consists of, are discussed. The close relation between the reflectance spectrum at the Brewster angle and an absorbance spectrum is illustrated by an experimental example.
