Talk:Chromophore

Since October 16, 2007 when the Chem drawing [needed] tag was placed in the Talk page, several images (diagrams) have been added to the article. Therefore, I have removed the Chem drawing tag from this Talk page. H Padleckas (talk) 06:49, 22 January 2012 (UTC)

Just pointing out that someone has added "{this paragraph needs correction: there are no d-orbitals in chlorophyll and the colour of amethyst is due to F-center}." to the text. I'm not qualified to make the recommended edit; but somebody should.

The beta-carotene structure is incorrect. — Preceding unsigned comment added by 134.84.165.148 (talk) 22:47, 7 March 2017 (UTC)

Colour or Spectra

Hi guys. I am a little bit confused in the definition of chromophore. The very first sentence in this term is A chromophore is the part of a molecule responsible for its color.[1] However, as in ref. [1] in IUPAC's website, it is about spectra, not only colour. I personally am not English native speaker so I am not sure about this word. Does the word colour only refer to visible light or all electromagnetic wave of the spectra? In the research of Infrared spectra, the molecule (or molecular segment) can also be called chromophore. I think maybe we should carefully consider about it whether or not it is suitable to 'simplify' the scientific term to a word in daily life. Zhaiyu.zhaiyu (talk) 14:07, 18 October 2017 (UTC)

Incorrect structure

The molecule identified as β-carotene, is not β-carotene. There is a methyl group missing on one of the ionone rings. The rings are identical in β-carotene. — Preceding unsigned comment added by 174.4.166.134 (talk) 05:53, 29 November 2017 (UTC)
