RAMAN AND SURFACE ENHANCED RAMAN SIGNALS OF THE SENSOR 1-(4-MERCAPTOPHENYL)-2,4,6-TRIPHENYLPYRIDINIUM PERCHLORATE

The sensor 1-(4-mercaptophenyl)-2,4,6-triphenylpyridinium Perchlorate compound was vibrationally characterized using Raman and the Surface-Enhanced Raman techniques, SERS and Shell-Isolated Nanoparticles-Enhanced Raman Spectroscopy (SHINERS). The Raman spectrum was analyzed and the band assignment w...
