摘要：

We have measured pressure broadening of the 118.455 cm-1 (3.551 THz) F1, 7 2+ ← F1, 5 2- rotational lines of OH by H2, He, N2, and O2. The measurements were made using tunable far-infrared spectroscopy. Broadening coefficients for N2 and O2 are presented for the temperature range 296 to 210 K; H2 and He broadening coefficients are presented for the temperature range of 296 to 80 K. We also determined accurate values for the line positions. The line positions and their 2θ uncertainties are 3 551 185.36(4) MHz (F = 4 ← 3) and 3 551 204.42(4) MHz F = 3 ← 2). © 1991.
