Absorption Spectrum of the Peptide Bond
In an earlier report (1) it was shown that a band characteristic of the peptide bond appeared in the ultraviolet and that values of the molar absorption coefficient (em) at 205 mp could be used to characterize this band. It was shown, for a series of proteins, that the contribution of each peptide bond (ep) to the molar absorption coefficient is fairly constant, lying between 2500 and 2800. The...

متن کاملLocalizing of a Four-Level Atom via Absorption Spectrum
We propose a scheme for localizing an atom in a four-level configuration inside a classical standing wave field, conditioned upon the measurement of frequency of a weak probe field. In the classical standing wave field, the interaction between the atom and the field is position dependent due to the Rabi-frequency of the driving field. Hence, as the absorption frequency of the probe field is mea...
متن کاملControlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...
متن کاملPeptide bond vibrational coupling.
Neutral trialanine (Ala3), which is geometrically constrained to have its peptide bond at Phi and Psi angles of alpha-helix and PPII-like conformers, are studied at the B3LYP/6-31+G(d,p) level of theory to examine vibrational interactions between adjacent peptide units. Delocalization of the amide I, amide II, and amide III3 vibrations are analyzed by calculating their potential energy distribu...
