How does Raman spectroscopy function to confirm the active ingredient in a drug substance?
Answer
Analyzing how laser light scatters off the molecules in the tablet
Raman spectroscopy is recognized as a frequently cited, high-tech method because it provides what is essentially a molecular fingerprint of the substance being analyzed. Its operational principle involves directing laser light onto the material within the drug tablet. The analysis focuses on how this incident laser light subsequently scatters off the molecules present. The resulting unique spectral pattern generated by this scattering allows investigators to confirm the exact identity and presence of the active ingredient, achieving a high degree of specificity necessary for definitive quality control.
