Abstract

Surface-enhanced Raman spectroscopy (SERS) has been applied to study lenticular pigments that are present in the eyes of certain diuranally active animals. Using Ag hydrosols pre-aggregated with NaClO₄, we have obtained SERS spectra from dilute solutions of various model pigment compounds, including kynurenine, N-formylkynrenine, 3-hydroxykyn-urenine, β-carboline, bityrosine, anthranilic acid, 3-hydroxyanthranilic acid, and oxindole. The results obtained from these model compounds show that SERS is a particularly sensitive technique for the identification of lens pigments. We also report a procedure that enables high-quality SERS data to be obtained for the yellow pigments in the lens homogenates of grey squirrels, ground squirrels, and chipmunks.
