"Raman, IR and surface-enhanced Raman spectroscopy of papaverine. An automated setup for in situ synthesis of the silver substrate and recording of the SER spectra";
Vibrational Spectroscopy, 36 (2004), S. 47 - 55.

Raman, IR, and surface-enhanced Raman scattering (SERS) were employed for the vibrational characterization of papaverine in the free and adsorbed state. The vibrational assignments were performed by means of d. functional theory (DFT) calcns. The adsorption of the mol. was concluded with the isoquinoline and the benzene ring close to the silver surface in tilted orientations. Employing a sequential injection system, an automatized setup was developed for reliable, accurate and rapid recording of FT-SER spectra. The colloidal silver substrate was synthesized in situ in a 2 mL quartz cuvette by reducing silver nitrate with hydroxylamine. The FT-SER spectrum of papaverine obtained with the developed exptl. setup exhibits the same characteristics as the SER spectrum obtained with a citrate reduced silver colloid.
