The rotational transition can be arranged as follows: v (J +1+ J)/{2(J + 1)} = B 2D1(J+1)? which is the equation of a straight line when the left-hand side is plotted against (J+1)?. The following wavenumbers of transitions (in cm) were observed for 12C16O: J: 1 2 3 4 v (cm"') 3.845033 7.689919 11.534510 15.378662 19.222223 a) Plot the graph b) Determine B, DJ and the equilibrium bond length of CO.
