Reactions of excited atomic iodine (52P½). Part 3.—Spectroscopic proof of the photochemical production of excited atoms in the banded region of the B3Πou +–X1Σ+g system, and a correlation with the reaction rate

Abstract

By restricting the flash photolysis of an I₂+ CO₂ mixture with light filters it was established by absorption spectroscopy that excited atoms are produced by photolysis in the banded region of the B³Π_ou⁺–X¹Σ⁺ _g system. The ratio of the concentrations of excited atoms produced in the banded and continuous regions were in close agreement with a calculation based on the previously derived quantum-yield/wavelength function.
