Emission spectral line intensity

[bejoynp]

Dear all

I need to calculate the intensity of the spectral line. I have data from NIST website:
wavelength, Aki (Einstein coefficient), gi, gk, Ei and Ek energy levels.

How do i go about

Thanks for your help

Are you talking about the energy of the photon released from the atomic transition .

 

[bejoynp]

The intensity of the radiation emitted when an electron transitions from a higher energy state to lower

(Absolute) Intensity normally refers to photons per time.
So: how many atoms are there? How are they excited? Do you know the (average) population of the levels? Do you mean relative or absolute intensitiy?
