SPR

My wife, a biochem major, was looking for a definition of SPR spectroscopy here, but didn't find one. Is it under a different name, or does it need to be added to the article? Jwrosenzweig 01:32, 9 Mar 2005 (UTC)

Thermal spectral smear?

If a substance is sufficiently hot, will the thermal-kinetic energy of its component atoms smear out its spectral lines? However, according to Boltzmann_distribution#typical speed, a gas would have to be circa 1e15 K for this to be a significant problem, at which point the gas will not be an ideal gas.

I <3 spectroscopy and I'm going to make this article beautiful

Since nobody has posted on talk page in... what 6 years?.. I don't know if anybody will see this.. buuut. I'm about to add tons of awesome stuff to this article.. .and to spectrometer — Preceding unsigned comment added by Popcrate (talk • contribs) 16:37, 1 February 2017 (UTC)[reply]

I'm excited to see another editor interested in the spectroscopy articles. I continue to watch and tweak these, but it has been a while since I was inspired to attempt a significant rework. If you have ideas that you'd like to discuss, I'm happy to be a sounding board. From looking at your recent edits, I have one question to consider and one concern. First, would the information you've added on Newton and Wollaston be more appropriate in the history of spectroscopy article? The top level spectroscopy article has to cover a lot, and so we have tried to include summary information here that links out to more in depth articles. Second, the two paragraphs you've added are direct quotes from the source. I'm glad that you provided good attribution for the source of this information. As discussed here, it is generally my goal to accurately summarize a source unless the source is so uniquely or well presented that it deserves to be quoted directly. I'm happy to keep the discussion going here or to start a broader discussion of how to improve the spectroscopy content on one of our user pages. ronningt (talk) 14:14, 5 February 2017 (UTC)[reply]

Question answer: Yes, it definitely would be more appropriate in the history section, and I share your concern about my edit for exactly the same reason. To the talk pages now, because otherwise the discussion will get incredibly confusing =) Popcrate (talk) 03:17, 17 February 2017 (UTC)[reply]

Titanium dioxide food additive to powdered sugar

It might be interesting and informative to add some commentary about how absorption and emission spectroscopy is utilized in food additives, such as the spectra of titanium dioxide (photo) which is added to powdered sugar for doughnuts due to the emission spectra which makes white powdered sugar adopt a "glow" attribute when added.

The use of such additives can be controversial (Dunkin doughnuts) but it is still a multi-billion dollar (globally) application of spectroscopy utilized in corporate science labs to make foods appealing and to acquire an economic advantage utilizing science -- and human behavioral psychology.
