Infrared spectroscopy (IR spectroscopy) is an optical technique that detects molecular bond vibrations and rotations upon absorption of infrared light. Because different chemical functional groups ...
Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon inelastic scattering of monochromatic light. Because different ...
Abstract: Terahertz (THz) technology has firmly established itself as an effective sensing and nondestructive testing (NDT) technique for the detection of substances and physicochemical evaluation of ...
