When searching for other words for the term «spectroscopy», there are many ideas that come to mind. From analytical chemistry to x-ray diffraction, there are a variety of synonyms that can be used to describe the process of spectroscopy. It is best to consider the specific application of spectroscopy when determining which synonym is most appropriate for a particular context. For example, if the goal is to measure the intensity of radiation, then a synonym such as photometry or radiometry would be a better choice than a synonym such as emission or reflection. Additionally, if the goal is to analyze the composition of a sample, then a synonym such as chromatography or mass spectroscopy would be a better choice than a synonym such as fluorescence or absorption. Ultimately, the best synonym for spectroscopy depends on the context in which it is being used.
