Quantitative Emission and Absorption,as a function of wavelength. Two steps are involved in this treatment. In the first step, a simple form of the equation of radiative transfer will be used to identify a new parameter, known as the spectral absorption coefficient, which will be seen as the governing quantity which characterizes emiss

A detailed study of the OH molecule is followed by more brief reviews of O., H.O, and hydrocarb

With these relationships in hand, it will become evident how spectrally resolved absorption (or emission) can be used as a nonintrusive means of measuring a variety of gasdynamic parameters, including: species concentration, pressure, temperature, density, and even flow velocity.

Introduction,vailable). That is, we accept that an atom or molecule may exist only in specific quantum states (characterized by quantum “numbers”), with each quantum state having a discrete amount of energy and angular momentum.

Rayleigh and Raman Spectra,onding to the energy of the interacting photon, scattering can occur with an incident photon of almost any energy. That is, for a molecule to absorb light, the light must generally be at specific wavelengths or frequencies. Scattering, on the other hand, can occur at almost any wavelength.

Bond Dissociation Energies, directly affect heats of formation and reaction. Dissociation energies thus also play key roles determining rates of reaction as a function of temperature. This chapter will give several examples of how spectroscopic information can reveal .. (of ground and excited electronic states).
