The purpose of my Senior Individualized Project was to detect and characterize the OH radical using Time-Of-Flight Mass Spectrometry. The radical was produced by photodissociation of hydrogen peroxide at 266 nm. It was then subject to photoexcitation at 309 nm and subsequent photoionization by Vacuum Ultraviolet Light at 125 nm, produced by four-wave resonant mixing in a mercury-filled heat pipe.
