UV Resonance Raman Finds Peptide Bond└Arg Side Chain Electronic

' INTRODUCTION
There is little understanding of the electronic transitions of
peptides and proteins.1└10
It is generally assumed that peptide
and protein electronic transitions result from the summation of
the electronic transitions of the constituent chromophores. The
peptide bond f * transitions have been characterized to a
limited extent, as have been the transitions of the different
isolated side chain chromophores.1└13
However, there has been
little attention paid to the potential coupling of the peptide bond
transitions to the side chain electronic transitions or to coupling
