A supersonic molecular beam optical Stark measurement of the à 2IIr-X̃2Σ band system of calcium monoacetylide CaCCH has been performed. The determined values of |μ| are 3.01 ±0.03 D and 2.41 ±0.02 D for the X̃2Σ + and Ã2II1/2 states, respectively. A simple electrostatic model quantitatively predicts the ground and excited state dipole moments.
