Homework Statement
The figure below shows the hyperfine structure in the transition 6s $^2S_{1/2}$ - 8p $^2P_{3/2}$ in 115In (I = 9/2). The measurement is made using a narrow-band tunable laser and a collimated atomic beam; hence the Doppler width is greatly reduced. The 6 components shown have the following frequencies 31, 112, 210, 8450, 8515 and 8596 MHz. Draw a schematic figure of the energy levels with the appropriate quantum numbers and show the allowed transitions. Determine the hyperfine constants, in MHz, for the two fine structure levels

Homework Equations
$$E_{hfs}=\frac{A}{2}[F(F+1) - J(J+1)-I(I+1)] (1)$$
The Attempt at a Solution
F=|J+I|,...,|J-I|. For the dubblet P that would be F=(6,5,4,3). So I have F,J and I.
Since I don't have energydifferences (I think), I'm not sure how to put up a equationsystem to solve for (1). Are there another formula/concept I should use instead?
*Note I'm a beginner at atomic physics, brand new to these concepts so maybe I'm missing something obvious*
