Raman Measurements in the Presence of Fluorescence

Not Accessible

Your library or personal account may give you access

Abstract

A method for eliminating the direct effects of fluorescence on Raman spectra is described. It is based upon the differences in widths of Raman and fluorescence peaks and is intended for applications of Raman measurements in chemical analysis. It involves only calculations that are carried out after the measurement has been made and does not require any instrumental enhancement beyond that normally used for Raman measurements. The extent of improvement that can be expected is shown, and the conditions under which its limits are reached are indicated. A technique involving an empirical correction is described which allows extension of these limits in certain cases.
