Raman Spectra of Amino Wagging Vibrational Modes in p-pi-Conjugated Molecules
(PEKING UNIV PRESS, 2013)Raman spectroscopy has been widely used as a non-destructive testing and molecular recognition technology, providing fingerprint information for chemical and biological molecular structures. One type of out-of-plane bending ... -
Raman spectra of MWCNTs and MWCNT-based H-2-adsorbing system
(PERGAMON-ELSEVIER SCIENCE LTD, 2002-05-14)Raman spectra were taken with an UV-vis Raman system on two types of multiwalled carbon nanotubes (MWCNTs, CH4-based) and MWCNTs (CO-based), grown catalytically with CH4 and CO as the carbon sources, respectively, and their ... -
Raman spectroscopic and quantum chemical study of hydrogen adsorption at platinum electrodes
(JOHN WILEY & SONS LTD, 1999-08-06)Hydrogen adsorption at platinum electrodes in acidic solution is investigated by confocal microprobe Raman spectroscopy and quantum chemistry calculation. Vibration for on-top adsorbed hydrogen against a platinum surface ... -
Raman Spectroscopic Investigation on TiO2-N719 Dye Interfaces Using Ag@TiO2 Nanoparticles and Potential Correlation Strategies
(WILEY-V C H VERLAG GMBH, 2013-Jul 2)Herein, we employ Ag@TiO2 core-shell nanoparticles for surface-enhanced Raman scattering (SERS) investigations of TiO2-N719 dye interfaces. In situ electrochemical SERS investigations of the Ag@TiO2-N719 interaction are ... -
Raman spectroscopic studies of Fe(CN)(6)(3-/4-) redox process at gold electrode surfaces
(HIGHER EDUCATION PRESS, 1997)By using surface-enhanced Raman spectroscopy, we studied the redox process of Fe(CN)(6)(3-/4-) couple on a roughened gold electrode surface, The results show that the Fe(CN)(6)(3-) is much more strongly adsorbed on the ... -
