Sentence examples for broadening coefficient from inspiring English sources

The precise measurement of pressure broadening coefficient γ in terms of the half width at half maximum is required in order to retrieve the atmospheric volume mixing ratio.

For the production of HO2, the mercury-photosensitized reaction of the H2 and O2 precursors was used to provide an optimum condition for measurement of the pressure broadening coefficient.

We determined angular momentum dependent collision broadening coefficients for each noble gas using the Lorentzian widths that were extracted from Voigt fits to the line shapes.

In comparison with those of other singlet molecules, the pressure broadening coefficients of the HO2 radical are not much affected by the existence of an unpaired electron.

The N2 and O2 pressure broadening coefficients of the pure rotational transitions at 625.66 GHz (NKaKc=101▒9 100▒10, J=10.5 10.5) and 649.70 GHz (NKaKc=102▒9 92▒8, J=9.5 8.5) in the vibronic ground state X2A′ of the perhydroxyl (HO2) radical have been determined by precise laboratory measurements.

The broadening coefficients as well as the temperature exponents are calculated using the semi-empirical approach.

The present broadening coefficients compared well with some of the prior measurements.

The air broadening coefficients for the 625.66 GHz and 649.70 GHz lines were estimated at γ air)=3.769±0.067 MHz and 3.298±0.099 MHz respectively, where the uncertainty includes possible systematic errors.

Experimentally obtained derivative spectrum is numerically integrated to reveal the original line shape and fitted with a nonlinear least squares fitting program to extract air broadening coefficients and line strength parameters.

The databank contains the line parameters (positions, intensities, self- and air-broadening coefficients, exponents of the temperature dependence of self- and air-broadening coefficients) of the principal isotopologue of NO2.

The results show that accurate self-broadening coefficients γ are obtained but that experimental uncertainties forbid any reliable determinations of the pressure-induced shifts δ due to the fact that they are about two order of magnitude smaller than γ.
