Infrared techniques encompass analytical and imaging methods that exploit the interaction of infrared (IR) radiation with matter to probe molecular structure, dynamics, and composition. Core approaches include mid-IR absorption spectroscopy (e.g., FTIR), near-IR spectroscopy, and IR microscopy, which measure vibrational transitions associated with specific chemical bonds and functional groups. Variants such as attenuated total reflectance (ATR), diffuse reflectance (DRIFTS), and infrared reflection–absorption spectroscopy (IRRAS) extend applicability to diverse sample types and surfaces. Time-resolved and nonlinear IR methods (e.g., pump–probe, 2D-IR) enable investigation of ultrafast processes and complex environments, supporting applications in materials science, chemistry, biology, and environmental analysis.
Cornell Engineering researchers have demonstrated that, by zapping a synthetic thin film with ultrafast pulses of low-frequency infrared light, they can cause its lattice to atomically expand and contract billions of times ...
