Collisional broadening and shift of five OH A2Σ+← X2Π (0-0) transitions in the Q1-branch, by H2O, O2, CO2, N2 and Ar, at 1220 K

JJ Girard, S Clees, RK Hanson - Journal of Quantitative Spectroscopy and …, 2020 - Elsevier
We report on the values of collisional broadening (2γ OH-A) and collisional shift (δ OH-A)
parameters for five transitions in the Q 1 branch of the A 2 Σ+← X 2 Π (0-0) band of the
hydroxyl radical (OH), considering five colliders (A= H 2 O, O 2, N 2, CO 2, Ar) at T OH= 1220
K. The lines analyzed include the strongest absorbing OH transitions from T= 300–3000 K,
notably covering the range of temperatures typically explored in combustion studies.
Furthermore, the targeted collision partners encompass the most commonly encountered …
