• A novel four nuclear magnetic resonance (NMR)-tube holder is described for quantitative Raman and resonance Raman spectroscopy. This cell has advantages over other divided cell designs in producing high precision quantitation and eliminating off-axis errors. Raman spectra were obtained for both absorbing and nonabsorbing solutions, and the results compared to those obtained using a single tube holder. The relative Raman intensities in a 1:1 mixture of benzene and chloroform taken in the single holder were within 6% of those of the pure solvents taken with the four NMR tube holder. The resonance Raman scattering cross section of chromate was determined to be within 6% of the value obtained from a single-tube holder. All of these errors in accuracy and precision are within the errors normally associated with the quantitative measurement of Raman cross sections. These results show that the four-tube holder can be used for precise and accurate measurement of both Raman and resonance Raman scattering.
