ABSTRACT
We studied the thermal broadening of Lb band of tyrosine and phenylalanine embedded in a trehalose matrix. Aim of this work is to obtain information on the effects of “trehalose coating” on the coupling of the electronic transition to low frequency modes in the surrounding of the chromophore. The results obtained for the two molecular complexes put in evidence that O-H groups are involved in blocking these structures within the solid trehalose matrix and shed light on the role played by hydrogen bonds on the interactions that keep “trehalose coated” proteins rigid and solid-like. © 2000 American Institute of Physics.
