Emission spectra of the hydroxyl radical have been recorded between 450 and 4200/cm at 0.0027/cm unapodized resolution from an air+oxygen+water vapor plasma, using a surface microwave discharge. The characteristics of the source are described. The emission spectra were recorded with the F.T. spectrometer using a GeCu detector and KCl beams plitter. High J values were observed both for the pure rotational transition in v=0 and v=1 vibrational levels, and for the rovibrational transition in the 0-1 and 1-2 bands. The set of line intensity data will be used to compute the electric dipole moment function of OH.
