Calculating hydrogen intensity lines how? tia sal22

[Rick T]

Greetings
I'm trying to calculate hydrogen intensity lines but not sure how?

I can calculate the wavelength and frequency for hydrogen between
levels
Example:
n3 to n2 Wavelength is 6.56e-7 and Frequency is 4.56e16 -Balmer
series

n5 to n3 Wavelength is 1.281e-6 and Frequency is 2.339e16 -Paschen
series

n8 to n5 Wavelength is 3.738e-6 and Frequency is 8.019e15 -Pfund
series

I used the Rydberg Formula to find Wavelength:
http://en.wikipedia.org/wiki/Rydberg_formula

And I used this formula for Frequency:
frequency=Speed of light/ wavelength

Does anyone now where I can find an example of how to calculate the
line intensity?

It doesn't have to be exact just trying to do some verification. If
the
values calculated match ratio wise with the numbers measured between
the different levels. just looking
for a ball park figure

This is not a simple question. How are you going to excite the line?

I am not an expert on the subject, but I think that you need to
calculate the matrix element value for a particular transition to get a
relative intensity. That is, in the presence of a known electric field
calculate the matrix element for transition from an upper to a lower
state and the emission of a photon. IIRC an decent book on quantum
mechanics has such a calculation. Schiff, for one.
