Abstract
The (0200)Σ+ ← (000)Σ+, (0220)Δ ← (010)Π, (0200)Σ+ ← (010)Π, and (010)Π ← (000)Σ+ bands in the [Formula: see text] electronic system of SrOH have been recorded at Doppler limited resolution using CW dye laser excitation with selective detection. Fluorescence from selected rotational levels of the [Formula: see text] and [Formula: see text] vibronic states has been dispersed, providing access to the (0200)Σ+ and (0220)Δ levels of the ground electronic state. Over 1200 line positions from all transitions were included in a global least-squares fit. The effects of a weak ℓ-type resonance between the ℓ = 0 and ℓ = 2 components of the ν2 = 2 vibrational level were observed in both electronic states and the off-diagonal matrix elements were evaluated in a case (b) basis. A previous analysis of the [Formula: see text] level that attributes the anomalous ℓ-type doubling to an electronic perturbation arising from the [Formula: see text] polyad is inconsistent with our experimental results.
