Abstract
- Abstract: Optical–optical double-resonance spectroscopy has been used to record a high-resolution spectrum of the transition of SrOH. Rotational and fine structure parameters have been determined for the state through a combined least-squares fit with the optical transition data and the millimeter-wave pure rotational data of the state. The spin-orbit constant of the state was found to be 24.6607cm−1, which is significantly smaller than in the à 2Π state. This change can be rationalized by the different atomic orbital character of the à 2Π and states. The values of the Λ-doubling constants in the state have been examined in terms of the pure procession model. The agreement between the calculated and observed Λ-doubling constants suggests that the state may form a unique perturber pair with the nearby state. [Copyright &y& Elsevier]
