Chlorine monoxide has been produced by photolysis of ozone in the presence of chlorine at a total pressure of 3.5 Torr. The absorption spectrum has been determined with a spectral resolution of 0.002 nm for all 35ClO (A2Π3/2v′-X2Π3/2v″ = 0) sub

The spectral features of electronic transitions between a bound upper state and a relatively flat lower state may be modeled using harmonic oscillator and particle-in-a-box wavefunctions. Evaluation of the Franck-Condon overlap integral yields an exp

The collisional deactivation of electronically excited iodine atoms, I (5P1/2), by CH4, C3H8, HBr, and DBr has been investigated using time‐resolved atomic resonance spectroscopy. This technique permits direct determination of the yield of I (5 2P3

When HgBr2 (2–45 mTorr) is photolyzed by the linearly polarized output of an ArF excimer laser (193 nm), the visible emission from the HgBr B 2Σ+ fragment is found to be linearly polarized. The degree of polarization is 11.9%±1.5%, in close agree

The collisional deactivation of O(2 1D2) by H2 and D2 was found to proceed with a rate constant 1.0±0.1×10−10 cm3 molecule−1 sec−1. The hydrogen atoms produced by O(2 1D2) +H2→OH+H were observed to react with the O3 source molecule with the

The production of bromine atoms in the ground, 42P3/2, and electronically excited, 42P1/2, states following the reactive deactivation of I(52P1/2) by Br2 was monitored by time‐resolved resonance absorption spectroscopy. Observation of the absorptio
