Sampling and Smoothing of Spectra

Abstract Anyone working with a spectrometer or similar system should be concerned with using it in the best possible way. This article is concerned with a portion of that problem, viz., the acquisition and treatment of the data. We describe herein what is going on in these various processes and show the dependence of various phenomena on the important parameters. On the basis of the evidence, we then recommend certain procedures and suggest appropriate values for the parameters involved.
