Raman vs. IR Spectroscopy Advantages Limitations

Raman vs. IR Spectroscopy Advantages Limitations

The differences between Raman and IR spectroscopy: The fundamental principles that govern each method - the Raman effect is weak, resulting from an inelastic raman scattering process that occurs when light interacts with molecules; IR spectroscopy is a stronger technique that relies on absorption of light by molecules. Molecules with functional groups that have strong dipoles …

Ultraviolet Disinfection Guidance Manual - EPA

UV Reactor Validation - a process by which a UV reactor's disinfection performance is determined relative to operating parameters that can be monitored. Reactors are validated to indicate that they achieve a certain delivered UV dose for a range of flow, UV intensity, and water quality conditions (e.g., UV transmittance).
