[SERS spectra of vitamin A acid in silver solution].

Abstract

Vitamin A acid (VAA) was firstly dissolved in chloroform, and then the organic solution containing the samples was mixed with silver sol at the desired concentration. After sufficient shaking, collect SERS spectra of VAA with silver sol layer solution. The attribution of the peaks was illustrated by comparing SERS spectra with NR (Normal Raman) spectra, and… (More)
