Title: THE MAGNETIC ROTATION SPECTRUM OF ACROLEIN: CIS AND TRANS ISOMERS
Creators: Bair, E. J.; Ramsay, D. A.
Issue Date: 1971
Abstract: The magnetic rotation spectrum of acrolein has been studied using an apparatus 1 m long and field strengths up to 5000 G. The effective path length was increased by a factor of 8 by the use of external multiple reflection mirrors. Five bands have been found at 4040, 4122, 4178, 4220 and 4322 \AA. The first four bands are assigned to the $^{3}$^{\prime\prime} --- $^{1}A$^{\prime} ($\pi^{*}$ - n) system of trans acrolein with the 0-0 band at 4122 A. The fifth band at 4322 \AA is assigned as the 0-0 band of the $^{3}A$^{\prime\prime} --- $^{1}A$^{\prime} ($\pi^{*}$ --- n) transition of the cis (or gauche) isomer. An energy level diagram showing the relative energies of the cis (or gauche) and trans isomers in the ground $^{1}A$^{\prime} and excited $^{1}A$^{\prime\prime} and $^{3}A$^{\prime\prime} ($\pi^{*}$ --- n) states will be shown.
