Nonphotochemical hole burning in hyperquenched glassy films of water: A pronounced deuteration effect.

The effects of deuteration on hole burning of aluminum phthalocyanine tetrasulfonate (APT) in glassy films of water is reported. Deuteration has no effect on the zero phonon hole width of the APT electronic transition, but a large effect on the hole burning kinetics. These effects are discussed in terms of the two level systems of glassy water. © 1996 American Institute of Physics. [ABSTRACT FROM AUTHOR]
