Webremained trapped. The HI was diluted to 0.5% in 1 atm of argon, and the bulb was wrapped in black cloth to prevent photochemical decomposition of HI. The HIrAr mixture was injected into the source region of the mass spectrometer through a 10 Hz repetition rate pulsed nozzle. To prevent decomposi-tion of the HI sample in the gas manifold behind the WebA photochemical reaction is a chemical reaction triggered when light energy is absorbed by a substance’s molecules. This response leads the molecules to experience a temporary excited state, thus altering their physical and chemical properties from the substance’s initial molecule.
