Reading an FT-IR Spectrum ②: How Should You Interpret the Peaks?

💡 In This Article What the x- and y-axes represent and why the overall spectrum matters Why peaks point in opposite directions in transmittance and absorbance spectra How to compare relative changes between samples and identify meaningful differences Why baseline correction, sample preparation, and ATR cleaning matter for reliable interpretation Before Memorizing Peak Positions, Understand … Continue reading Reading an FT-IR Spectrum ②: How Should You Interpret the Peaks? →

Reading an FT-IR Spectrum ①: What Does FT-IR Actually Tell Us?

💡 In This Article The basic principle of Fourier transform infrared (FT-IR) spectroscopy How FT-IR can be used to monitor epoxy curing reactions The differences between the KBr pellet method and attenuated total reflectance (ATR) In previous articles, we explored how thermal analysis techniques such as DSC and DMA help characterize the thermal behavior and … Continue reading Reading an FT-IR Spectrum ①: What Does FT-IR Actually Tell Us? →
