Effect of Ring Size on the Far Ultraviolet Absorption and Photolysis of Cyclic Ethers

Abstract

Absorption curves, tabulated extinction coefficients, and oscillator strengths are given for trimethylene oxide, ethylene oxide, and formaldehyde vapor in the spectral range 2000–1550 A. A comparison is made of the spectra and photochemical stability of these compounds with those of previously determined five- and six-membered ring ethers.
