摘要: Widths of lines in the (0, 90, 0)–(0, 01, 0) band HCO ? 2A\–? 2A′ transition are recorded using a single‐mode dye laser, revealing strong dependence on rotational quantum number N. The radical is produced radio frequency discharge acetaldehyde (CH3CHO) vapor and ?–? 570–630 nm region detected by laser‐induced changes impedance. variation widths with N interpreted terms Coriolis interaction K‐type resonance 0)Σ(K′ = level nearby strongly predissociated Π(K′ 1) Δ(K′ 2) levels, respectively, upper state.
