Abstract

A few species have been firmly identified in spectra of TNOs (including Pluto and Charon) and Centaurs. These are: ices of water, nitrogen, carbon monoxide, and methane. In addition, an absorption at 2.3 micron detected in spectra of two objects (Centaur Pholus and TNO 55638) has been attributed to methanol (or a photolytic product of methanol) ice, and an absorption at 2.2 micron seen in spectra of Charon (and maybe Quaoar) has been tentatively assigned to a mixture of ammonia and ammonia hydrate. Furthermore, a few silicates (anhydrous and hydrous) and a few organics have been considered in spectral models of some of these objects to account for broad unidentified signatures, to reproduce spectral slopes (shapes) or to explain the measured low albedos. We briefly review the laboratory data that have been used so far to interpret the spectra and we discuss what is missing.
