Publisher:Ohio State University
The use of divided and rotating liquid (or powder) cells or the use of a rotating lens system permits the near-simultaneous measurement of several channels (typically four) of Raman spectra. These devices ensure that frequency measurement errors between the different channels are eliminated. Our Raman system permits the simultaneous recording of the parallel and perpendicular polarized spectra of two different samples and the photon-counting electronics permit linear combinations of the spectra to be made. Thus, for example, the isotropic and anisotropic components of the Raman bands for the two samples may also be recorded simultaneously. Other linear combinations permit Raman difference spectra to be recorded so that very accurate frequency shifts measurements may be made. Various applications, such as the determination of frequency shifts resulting from isotopic dilution, will be described.
