✦ Synopsis

Abstract

The hydrated electron (e^−^~aq~) and hydroxyl radical rate constants with 18 acrylate‐, methacrylate‐, crotonate‐, fumarate‐ and maleate esters are discussed. The constants approach the diffusion‐controlled limit. k(e^−^~aq~) and k(OH) change in opposite direction; if k(e^−^~aq~) is high then k(OH) is small. This tendency is connected with the nucleophilic character of e^−^~aq~ and the electrophilic character of OH, although the site of attack of e^−^~aq~ and OH is different: carbonyl versus vinyl group.

## Abstract The rate constant for the gas‐phase reaction of hydroxyl radical with isopropyl isocyanate (IIC) has been measured, relative to toluene, in the T = 287–321 K range at atmospheric pressure in air. Ultraviolet photolysis of methyl nitrite served as the source of hydroxyl radical. The expe

The relative rate technique has been used to measure the hydroxyl radical (OH) reaction rate constant of ethyl 3-ethoxypropionate (EEP, CH 3 CH 2 -O -CH 2 CH 2 C(O)O -CH 2 CH 3 ). EEP reacts with OH with a bimolecular rate constant of (22.9 Ϯ 7.4) ϫ 10 Ϫ12 cm 3 molecule Ϫ1 s Ϫ1 at 297 Ϯ 3 K and 1 at
