“…The majority of these studies utilized N 2 , O 2 , and ''air'' as collision partners for obvious atmospheric applications. Recently, we reported new O 2 pressure broadening coefficients, which expanded the collision space to include the molecular collision partners CO, CO 2 , and SF 6 [20]. Currently, no complete systematic study of pressure broadening in the O 2 A-band by the noble gases has appeared in the refereed literature.…”
