## Abstract The kinetics of the reactions of ground state oxygen atoms with __trans__β2βbutene, __cis__β2βbutene, 2βmethylpropene, 2βmethylβ2βbutene, and 2,3βdimethylβ2βbutene was investigated in the temperature range 200 to 370K. In this range, the rate constants are (in units 10^β11^ cm^3^ s^β1^)
It is shown that the fluorescence-excitation spectrum of tetramethylethylene (2,3dimethyl-2.butene) can be vibrationally resolved in a cold beam. A partial vibrational assignment, based on the observed analogy with the absorption spectrum of ethylened,, indicates that the fluorescence is excited by
2,3-Dimethyl-2-butene (TME) was used as a model compound for polyisoprene in a study of 2-mercaptobenzothiazole (MBT)-accelerated sulfur vulcanization. Mixes that contained curatives only were heated in a DSC to various temperatures, while those that also contained TME were heated isothermally at 15
