Microwave spectrum of 35ClCN in excited vibrational states

The microwave rotational spectrum of (ClCN)-Cl-35 in the region 80-120 GHz has been reexamined. Rotational constants for the vibrational states (0v(v)0) with upsilon up to 5 and for the mixed states (02(0)0)(10(0)0), (11(1)0)(03(1)0) and (03(1)0)(11(1)0) have been obtained. Other vibrational states have been given a tentative assignment.
