Hydroxyl concentration prof'des have been measured in a low-pressure flat propane/oxygen flame by mass spectrometric analysis (with molecular beam sampling) and by ultraviolet (UV) absorption spectroscopy. Agreement between the two profiles is very good except for the preheating zone of the flame fo
