👉 Spectrological is a scientific term that refers to the measurement of light intensity and wavelength. It involves the study of how different wavelengths of light combine in various combinations, which can be useful for understanding the behavior of chemical reactions or other phenomena. Spectroscopy is a branch of physics that uses the principles of quantum mechanics to study matter at very low temperatures (less than 100 Kelvin) and high pressures (greater than 1 bar).
