Cardiolipin binds nonyl acridine orange by aggregating the dye at exposed hydrophobic domains on bilayer surfaces
It is established that NAO does not exhibit a pK in a pH range between 2.3 and 10.0 and a model is proposed in which the nonyl group inserts in the bilayer at the hydrophobic surface generated by the presence of four chains on the phospholipid. Expand
Charge‐transfer theory of surface enhanced Raman spectroscopy: Herzberg–Teller contributions
A comprehensive development of the charge‐transfer theory of surface enhanced Raman scattering (SERS) is presented. We incorporate the Herzberg–Teller mixing of zero‐order Born–Oppenheimer electronicExpand
A Unified Approach to Surface-Enhanced Raman Spectroscopy
We present a unified expression for surface-enhanced Raman spectroscopy (SERS). The expression contains a product of three resonance denominators, representing the surface plasmon resonance, theExpand
Raman and surface-enhanced Raman spectra of flavone and several hydroxy derivatives
The Raman and surface-enhanced Raman spectra (SERS) of flavone and three of its hydroxy derivatives, 3-hydroxyflavone (3-HF) and 5-hydroxyflavone (5-HF) and quercetin (3,5,7,3 � ,4 �Expand
A unified view of surface-enhanced Raman scattering.
By examining breakdowns in the Born-Oppenheimer approximation, Herzberg-Teller coupling is used to derive a single expression for SERS, which includes contributions from all three resonances, and it is shown that these three types of resonances are intimately linked by Herzberg/Teller vibronic coupling terms and cannot be considered separately.

The theory of surface-enhanced Raman scattering.
By considering the molecule and metal to form a conjoined system, an expression for the observed Raman spectrum in surface-enhanced Raman scattering is derived and it is shown that the SERS spectrum can vary considerably with excitation wavelength, depending on which plasmon and/or charge-transfer resonance is excited.

Electrochemical and spectral studies of the reactions of aquocobalamin with nitric oxide and nitrite ion.
UV-vis spectrophotometry and mass spectroscopy were used to show that C Bl(I) reduces NO to form Cbl(II)-NO and N(2)O and N-2, and this reaction is involved in the cyclic voltammetry of cobalamin in the presence of excess NO where a catalytic reduction of NO occurs involving the cycling of Cbl-II-NO/Cbl(I).

Theory of Surface-Enhanced Raman Scattering in Semiconductors
We develop an analytical expression for the lowest order nonzero contribution to the surface-enhanced Raman spectrum from a system composed of a molecule adsorbed on a semiconductor nanoparticle. WeExpand

UV-vis stopped-flow results show that glutathionylcobalamin can react with nitric oxide at pH 7 to form nitrosylcob(II)alamin in a reaction second-order overall. From kinetic studies we suggest thatExpand
