Title: Terahertz spectroscopy of aqueous L-Proline in reverse micelles
Published: November 21, 2008
Abstract: A new method for obtaining room temperature terahertz (THz) absorption spectra of aqueous-phase biomolecules in the frequency range 1 THz to 21 THz (35 cm-1 to 700 cm-1) is reported. The spectrum for L-Proline was acquired by solvating the amino acid within the nanometer-sized interior water pool of reverse micelles dispersed in transparent n-heptane. Terahertz spectra of H2O, D2O, and the effect of L-Proline concentration and micelle size are discussed. The results compared to spectra of solid-phase L-Proline and Gaussian calculations.
