Heating Molecules
« on: December 28, 2006, 07:28:30 PM »
Is it possible to heat one or two molecules only so that they produce a distinct colour? Like heating one molecule so that it's blue and the next so that it's purple... or would it have to be different gases?

Hi P-man,

Thats a really good question.  This area is called Thermochromic chemistry. 

A link with some more information about this area is http://en.wikipedia.org/wiki/Thermochromics.  It is commonly used in paper, paints and ink.

I am not sure if Television tubes (the phosphorous coating) could be considered Thermochromic, but it may.  The resolution on a Television screen would have differences in colours by very small distances.

I hope this helps,

Eugene
