Raman spectrum intensity

WebbRaman spectra were obtained with a dispersive microscope (Bruker Sen-terra). The samples were excited by a laser at 532 nm with 20 mW and the Raman intensity recorded in the spectral range of 50-1542 cm−1. The laser beam was focused by a ×20 objective lens, and the intensity at the detector was integrated for 2 seconds.
