## Homework Statement

The J=0 to J=1 transition fro 12C16O carbon monoxide occurs at 1.153x10

^{5}MHz. Calculate the value of the bond length in CO.

## Homework Equations

2B = h/(4π

^{2}I)

μ = m1*m2/(m1+m2)

I = μr

^{2}

## The Attempt at a Solution

I = 6.61x10

^{-34}/ (4*π

^{2}*1.153x10

^{8}) = 1.45x10

^{-43}kg m

^{2}

μ = 12.01*16.00/(12.01+16.00) *1.661x10

^{-27}= 1.14x10

^{-26}kg

r = √(I/μ) = √(1.45x10

^{-43}/1.14x10

^{-26}) = 2.52x10

^{-9}m or 2520 pm, which is significantly larger than the observed value of 113 pm.

Does anyone see where I went wrong?

Thanks!
