Abstract

The permanent electric dipole moments of CaOH and SrOH in their X 2Σ+, A 2Π3/2, A 2Π1/2, and B 2Σ+ states have been measured using the technique of supersonic molecular beam optical Stark spectroscopy. For CaOH the values obtained were μ(X 2Σ+) = 1.465 (61)D, μ(A 2Π 1/2) = 0.836(32)D,μ(A 2Π3/2) = 0.766(24)D, and μ(B 2Σ+) =0.744(84)D, while for SrOH the values were μ(X 2Σ+) = 1.900(14)D, μ(A 2Π1/2) = 0.590(45)D, μ(A 2Π 3/2) = 0.424(5)D, and μ(B 2Σ+) = 0.396(61)D. The results are compared with values from a recent ab initio calculation for CaOH and with the predictions of a semiempirical electrostatic polarization model.
