A supersonic molecular beam optical Stark measurement of the Ã 2Π r-X̃ 2Σ + 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 X̃ 2Σ + and Ã 2Π 1/2 states, respectively. A simple electrostatic model quantitatively predicts the ground and excited state dipole moments.
