| الملخص≠ | Attenuated Total Reflectance (ATR) Fourier Transform Infrared (FTIR) spectroscopy is a variant of conventional FTIR that measures infrared absorption through evanescent-wave interrogation of samples in direct contact with a high-refractive-index crystal. Developed by Harrick and Fahrenfort in the 1960s, ATR-FTIR is now the dominant form of FTIR spectroscopy, enabling rapid, non-destructive characterization of organic compounds, polymers, coatings, and biological materials without extensive sample preparation. | Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometry is an advanced analytical technique that combines magnetic confinement of ions with Fourier transform data processing to achieve exceptional mass accuracy and resolution. Developed by Comisarow and Marshall in 1974, FT-ICR-MS enables the determination of exact masses and elemental compositions of complex molecules, making it invaluable for environmental chemistry, metabolomics, petroleum characterization, and structural elucidation of unknowns. | Surface-Enhanced Raman Spectroscopy (SERS) amplifies weak Raman signals by many orders of magnitude when analyte molecules are adsorbed on specially prepared metal (typically silver or gold) nanostructured surfaces. Discovered by Fleischmann, Hendra, and McQuillan in 1974, SERS enables detection of vibrational signatures of single molecules and ultra-trace contaminants, revolutionizing analytical chemistry and forensics. |
