A new spectral line intensity formula for optical emission spectroscopy was presented by Dr:s Bo Thelin (experimental physicist) and Sten Yngström (theoretical physicist) at the beginning of the 1980:s. This formula has shown very good agreement between experiments (ref 1) and the new theory (ref 2). These references are summaries of earlier papers.


I = K \ left (frac { v^2 }{ c^2 }\ right ) \ e^left (\ frac { -J}{ k \ T \ right )} \

\ left (\ e^left ( \ frac { h \ v }{ k \ T \right -  \ 1)^-1

K includes transition rates and element concentration,v=frequency,J=ionisation energy and T=temperature —Preceding unsigned comment added by 79.138.138.183 (talk) 00:32, 9 March 2008 (UTC)[reply]

Many independent experimental methods strongly support the new formula, while the standard intensity formula with the Boltzmann term (upper energy level), deviates very much from experiments.
