PRESSURE BROADENING OF THE 83.869 CM(-1) ROTATIONAL LINES OF OH BY N-2, O-2, H-2, AND HE

摘要

We present pressure broadening coefficients of the 83.869 cm(-1) (2.514 THz) F-1, 5/2(-) <-- F-1, 3/2(+) rotational lines of OH by N-2, O-2, H-2, and He at 293 and 192 K. We also remeasured the position of the manifold of lines, with results that are in excellent agreement with a previous accurate determination. The frequency of the strongest component of the transition (F = 2 <-- 3) and its 2 sigma uncertainty is 2,514,316.37(3) MHz. [References: 11]
