Spectroscopic data refers to data collected using spectroscopy techniques, which involve analyzing the interactions between matter and electromagnetic radiation. Spectroscopy is used to study the composition, structure, and properties of materials by measuring the absorption, emission, or scattering of light. Spectroscopic data can provide information about the chemical composition, molecular structure, and physical properties of a sample, making it a valuable tool in a wide range of scientific disciplines, including chemistry, physics, and biochemistry. This data can be used to identify unknown substances, determine the concentration of chemicals in a sample, and investigate the behavior of molecules and atoms. Spectroscopic data is typically collected using instruments such as spectrometers, which measure the intensity of light at different wavelengths, and the resulting data can be analyzed using various mathematical techniques to extract useful information.
