Line strengths were measured for four transitions of the HO radical near 2.93 ..mu..m in the fundamental vibration-rotation band using a tunable infrared diode laser coupled to a molecular modulation spectrometer. The hydroxyl radical was produced by modulated photolysis of O/sub 3/ at 2537 A in the presence of H/sub 2/O, and its number density obtained from numerical simulation of the complete photochemical system. The strongest line observed was at 3407.607 cm/sup -1/ with a measured line strength of 3.3 +- 1.5 x 10/sup -20/ cm/sup 2/ molecule/sup -1/ cm/sup -1/.
