The lowest frequency microwave transition of the 1²CO molecule occurs at 3.8626 cm-'. This transition corresponds to the J= 0 →J= 1 rotational transition. (a) From theJ=0→J=1 transition energy, calculate the rotational constant (in cml) of the 12CO molecule. (b) What is the energy (in units of cm-') for the J= 1 → J=2 rotational transition of 12CO? (c) Calculate the rotational constant for the 1³CO molecule. (d) Using the 12CO or 1³CO rotational constant, calculate the bond length for CO.
