17. It was found that continuous photoexcitation of the sample in air induces degradation, as evidenced by a blue shift of the TA bleaching and a decrease in the magnitude of the bleach. When the cell is assembled in an inert atmosphere of helium and then examined by TA spectroscopy, the TA bleaching position and magnitude remain stable even after hours of continuous photoexcitation.
