I HAVE during the last summer, at Macdonald Physical Laboratory, McGill University, examined the Raman spectra of benzene and toluene under the fairly high dispersion of 4-5 A. per mm. This work ...

These Raman spectra can be clearly distinguished. Figure 1. Principles of Raman spectroscopy, showing spectra of five similar molecules – Acetone, Ethanol, Dimethyl Sulfoxide, Ethyl Acetate, and ...

In Metrohm Raman, a 1:1 v/v mixture of Toluene:Acetonitrile is used for x-axis calibration, with an acceptance criterion of ±2 cm –1, surpassing criteria for handheld Raman systems (±2.5 established ...
