Detection of n-π* transitions in pyridine and pyrazine in polyethylene solution by linear dichroism
Journal article, 1973

Studies of linear dichroism, using a differential technique, on pyridine and pyrazine, quasi-oriented in stretched polymer matrices, give evidence for the energy positions of the n-π* transitions. These molecules are mainly oriented in the same way as benzene, i.e., the orientation axes in the molecular plane are almost degenerate, and the out-of-plane polarized transitions appear as negative linear dichroism components.
