The Orientation of the Magnetic Axes of Quinoxaline and 2,3-Dichloroquinoxaline Triplets in a Durene Host Crystal from PMDR Methods.
Abstract
The polarizations of the zero-field (zf) transitions of quinoxaline and 2,3-dichloroquinoxaline in durene have been measured at 1.6K by phosphorescence microwave double resonance methods. From the results, the orientation of the magnetic axes of the triplet state of these molecules relative to the host lattice has been determined. Quinoxaline is found to dissolve substitutionally in durene, as has been concluded from ESR, while the magnetic axes of 2,3-dichloroquinoxaline are found to be rotated by 12 + or - 4 degrees around the short molecular axis.
