A Study of Electronically Excited Nitrogen Dioxide in its First Predissociation Region: Fluorescence Emission, Lifetimes, and Electronic Quenching.

Abstract

Fluorescence behavior of NO2 in the first predissociation region (3979 to 4200 A) was studied in great detail with fluorescence excitation spectroscopy and the phase-shift technique for the lifetimes measurement. The predissociation limit is determined to be about 3980 A. A fluorescing species with a constant intrinsic lifetime of about 7 x .00007 sec and a predissociating species with a very short lifetime (10 to the minus 7 power sec) are found. (Author)
