Abstract

We report precision measurements and calculations of several parameters of the A 2 state of the OH free radical. Data from quantum beats in the fluorescence of laser-excited molecules and direct optical spectroscopy have been combined to yield the following values for the parameters of our model Hamiltonian: =6862(43) MHz, b+c3=774.1(0.4) MHz, c=168.9(0.8) MHz, gr=0.00248(0.6)B, and gA=0.0242(11)B. Calculations that include coupling to the ground X 2 states through rotational or spin-orbit interactions produce estimates of these parameters that agree very well for all except gA.
