👉 In physics, an antispectroscopic property is a property that does not depend on the frequency of light. This means that two substances with different properties will have different spectra when they are excited by different frequencies of light. For example, two substances with the same color but different properties (e.g., one substance being transparent and the other being opaque) will have different colors when they are subjected to the same light. Antispectroscopic properties can be useful in various contexts, including spectroscopy
