The very short - lived ozone depleting substance CHBr 3 ( bromoform ) : Revised UV absorption spectrum , atmospheric lifetime and ozone depletion potential

Localizing 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...

Controlling 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...

(bromoform): revised UV absorption spectrum, atmospheric lifetime and ozone depletion potential

CHBr3 (bromoform) is a short-lived atmospheric trace compound that is primarily of natural origin and is a source of reactive bromine in both the troposphere and stratosphere. Estimating the overall atmospheric impact of CHBr3 and its transport to the stratosphere requires a thorough understanding of its atmospheric loss processes, which are primarily UV photolysis and reaction with the OH radi...

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...
