jk I'm all about that bread @danishcookies@computerfairi.es

@danishcookies @ben Well I mean, you can take a small sample and bring it up to test conditions without lighting up the entire gender...
You could just do a really low-energy ionization test, but then you'll miss anything that's solid or liquid at room temperature.
Raman spectrometry can work too, and can also identify cold molecular compositions that a hot emission spectrum will miss.
If your gender is crystalline when solid, there's always X-ray crystallography.

@ben cubic spline interpolation is popular, but probably not a good idea in this case because gender emission spectra can depend on a lot of unpredictable higher-order effects. even a superposition of delta functions gives you a more useful approximation.

and, of course, keep in mind that gender spectra can vary a lot with degree of excitation, pressure, and temperature. ensure your gender is in a thermal steady-state before taking sensitive measurements.

@ben let's not forget the polynomial approximation, either, that can give you as many vector components as you like and will eventually fit most genders quite well across the visible spectrum if you really crank up the number of terms.
