Thermal infrared spectroscopy (TIRS) is an analytical technique used to study the infrared spectral characteristics of materials based on their thermal emissions. This technique measures the intensity of infrared radiation emitted by a sample at a specific temperature, typically in the mid-infrared range (approximately 3-30 micrometers, or 3000-30,000 nanometers).
