摘要:
A unique method for obtaining angular resolved Raman spectra is described, the purpose of which will be to study the angular dependence of the surface enhanced Raman effect from molecules adsorbed on metal substrates. Our design employs two flexible fiber optic bundle probes which are optically coupled to the laser and the monochromator respectively. The probes which define the incident and detected angular resolution at 20°, can be independently positioned in 45° azimuthal angle increments and at 0°, 22 1/2°, 45°, and 67 1/2° with respect to the sample surface normal. In a test of the performance of the system, the angular dependence of the Raman intensity from the 992 cm−1mode of benzene was recorded. The results are in excellent agreement with previous data, thus demonstrating the practicality of our device.
