Hello,
I was wondering if anyone has tried to observe the spectra from classic
intro-chem flame tests. I tried this morning, with just a simple
diffraction grating and, for example, some sodium chloride salt (which
glows nicely yellow for the sodium) but was unable to observe any of the
sodium spectral lines at all: the yellow was just one big smudge. I
thought that either 1) I was missing some more careful method to observe
it or 2) that, because of the complexity of the system (sodium, chlorine,
methane in the bunsen burner, oxidation, etc...) that the narrow spectra
lines get washed out in the interactions.
Anyone ever do it, or, know of a more concrete reason it *won't* work?
