## Homework Statement

So I'm stuck on part (ii) where we have to solve the rotational energy levels.

## The Attempt at a Solution

Calculate the reduced mass then divide by avagardos number and x1000 to get it into kg per molecule - 1.139*10^-26

Then I use this value to work out I and get 1.457*10^-46

Then, B can be calculated I got 603.52 for this

Next, D = 187.7

Put all this into the equation for E and I end up with 460.24 but the actual answer for this case (j=1) was 3.84cm^-1.

Please let me know if there's anything I can clear up.
