Abstract
A method is provided of obtaining a vapor phase spectrum of a compound. The method comprises providing an isolated condensed phase sample of the compound, vaporizing the sample and supplying the vapor to an absorption cell of a spectrometer. A rate at which vapor enters the absorption cell is determined and a steady state concentration of vapor in the absorption cell is established. The spectrum of the vapor is then measured.
