Abstract
The article presents the results of calculation of vibrational and rotational terms of X2Π and B2Σ+ electronic states of phosphorus oxide (PO) molecule. The absorption spectrum corresponding to electronic transition B2Σ+ (\({v}{\kern 1pt} '\) = 0) – X2Π (\({v}{\kern 1pt} ''\) = 0) is calculated. The efficiency of laser excitation of PO molecules is estimated depending on the spectral parameters of radiation. It is established that the efficiency of excitation of the electronic transition B2Σ+ (\({v}{\kern 1pt} '\) = 0) – X2Π (\({v}{\kern 1pt} ''\) = 0) of PO molecule is approximately an order of magnitude lower than that of A2Σ+ (\({v}{\kern 1pt} '\) = 0) – X2Π (\({v}{\kern 1pt} ''\) = 0) transition. The results are of practical importance from the point of view of choosing the optimal scheme for laser excitation of fluorescence of PO fragments in remote detection of organophosphates.
期刊介绍:
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
