But all kinds of complicated material-properties can affect the color our eyes see (to my understanding). That alone wouldn't be useful in this way. It's the fact that these signatures exist at an elemental level, and are consistent across all contexts, and can be teased apart at a cosmic scale that makes the technique so powerful.
- sandworm101 6y agoSpectroscopy isn't simple. There are huge grey areas. Very well-defined signatures often overlap into a blurry mess of lines. Even within a single element, say hydrogen, there can be different signatures for different ionization states. Rather than clean detections there is often much opinion and debate, for years, before spectroscopy evidence is agreed as a legitimate detection of a substance.
