Interfacial Molecular-level Structures of Polymers and Biomacromolecules Revealed via Sum Frequency Generation Vibrational Spectroscopy
Published on: August 13, 2019
Abstract:
From an analysis of the high-resolution spectrum of the 3nu(3) manifold of SF(6) , we have determined the anharmonicity constants to be (in reciprocal centimeters) X(33) =-1.7426, G(33)=0.9188, and T(33) = -0.24635. By using these constants, one can for the first time to our knowledge accurately predict the energies of the lower-vibrational sublevels of the nu(3) ladder and determine the pathways for multiple-photon absorption.
