| Outline of Final Research Achievements |
New measurement methods were established to develop simple quantitative analysis methods using Raman spectroscopy. The Raman intensity ratio of the sample to the standard was found to be constant even when the laser power was changed. “Double laser Raman spectroscopy” was developed as a quantitative analysis method without a standard. The light-source laser beam was separated into two parts by a beam splitter. One part was used for monitoring the laser power and the other was used as excitation light for measuring the Raman spectrum. The Raman spectrum was measured while monitoring the laser power. The Raman intensity was corrected by dividing it by the monitored laser power. The ratio between the Raman intensity and the monitored laser power was constant even if the laser power was changed. This result shows that Raman intensity can be corrected by the monitored laser power. The relationship between the Raman intensity ratio and the concentration shows good linearity in this method.
