Homework Statement
The bond length of CO is 1.128 Å. At what wavenumbers do the first three rotational transitions appear
Homework Equations
μ= (m1m2/m1+m2)
I = μr0^2
B= h/(8∏^2)IbC
ΔE = 2B (J+1)
The Attempt at a Solution
For the first equation I got
(12 x 16) / 28 = [(6.857 /1000)/ avagadro number] = 1.138 x 10^-26
For the second equation I got
(1.138 x 10^-26) x (1.128 x 10^-10)^2 = 1.44 x 10^-46 kg/m^2
For the third equation I got
planck's constant / [(8∏^2) x (1.44 x 10^-46 ) x (speed of light)] = 1.93cm^-1
I honestly don't know what to do after this please help
really appreciated and thank you very much
