✦ Synopsis

Pure rotational transitions have been used to probe high rotational states of OH(X 'H, v=O) formed in the reaction H+O+ OH+0 at 2.6 eV collision energy. The infrared diode absorption/gain technique is complementary to laser-induced fluorescence (LIF) and particularly useful for probing those high rotational levels where predissociation of the A 'Z+ state of OH limits the accuracy of LIF data. The rotational distribution is monotonically decreasing at N>25 in the title reaction, where trajectory calculations had suggested a local maximum
